Description

Technical Field

[0001] Embodiments of the present application relate to the field of computer technology, and in particular, to a data display method and an electronic device. Background Art

[0002] Currently, when visualizing a data set with a large amount of data, a scatter plot of the data set is mainly used. This display method can visualize the classification of the data set, the features and distances between various types of data, etc. However, users cannot view the specific information of each data point based on this scatter plot of the data set. Therefore, when users have objections to the classification results of certain data, it is difficult to detect and locate the problematic data points. If all the data is directly displayed, the device will have data superposition due to cramped display space and small distances between data, making it impossible to view clearly; moreover, when the amount of data is too large, the display efficiency and performance of the electronic device will be greatly reduced, and it may even crash directly.

[0047] When combined with the accompanying drawings, the above and other aspects, features, and advantages of the present disclosure will become more apparent in view of the following detailed description.

[0048] Hereinafter, specific embodiments of the present disclosure will be described with reference to the accompanying drawings; however, it should be understood that the disclosed embodiments are merely examples of the present disclosure and can be implemented in various ways. Well-known and / or repetitive functions and structures are not described in detail to avoid unnecessary or redundant details from obscuring the present disclosure. Therefore, the specific structural and functional details disclosed herein are not intended to be limiting, but merely as a basis for the claims and a representative basis for teaching those skilled in the art to use the present disclosure in substantially any suitable detailed structure in a variety of ways.

[0049] This specification may use phrases such as "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0050] Next, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0051] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a data display method, including:

[0052] Determine a first region in the dataset scatter plot;

[0053] Perform a fisheye distortion transformation on the first region to form a second region, where the display state of the second region is different from that of the first region;

[0054] Determine the display position of each data point in the second region;

[0055] Obtain the data graph of each data point in the second region;

[0056] Display the corresponding data graph based on the display position of each data point.

[0057] For example, as Figure 1 , Figure 2 and Figure 3 shown, the data display method in this embodiment can be applied to the display of a dataset scatter plot. The dataset scatter plot can be obtained from a third party or prepared by a user using an electronic device. Specifically, features can be obtained and processed through numericalization, standardization, normalization, etc., and feature selection can be performed simultaneously. Then, methods such as Uniform Manifold Approximation and Projection (UMAP) are used to reduce the dimension of the selected features, reducing the high-dimensional features to 2D or 3D. After that, the dataset scatter plot can be directly drawn based on the dimension-reduced features, or clustering analysis, classification processing, etc. can be performed on the dimension-reduced features first, and then the dataset scatter plot can be drawn. For the drawn dataset scatter plot, the user can manipulate it for zooming and panning, as Figure 5As shown, by magnifying the scatter plot, the dispersion degree of the data is increased for clearer viewing of the data. Further, after obtaining the scatter plot of the data set, the user can select the area he hopes to view from the scatter plot of the data set as the first area, or determine the first area in the scatter plot of the data set based on the default data graph viewing option. For example, the default option is to select the first coordinate area on the scatter plot of the data set as the first area, which can be located in the central area of the scatter plot or in the edge area of the scatter plot. Moreover, after the data graph is displayed with the first coordinate area as the first area, the next second coordinate area can be selected as the first area to continue the display of the data graph until the data graph has been displayed in all areas of the scatter plot. Or it can also be to determine the first area based on the preset options pre-customized by the user. For example, the central area of the scatter plot is determined as the first area each time, or the area where the data point density meets the threshold is used as the first area, or the area where the characteristic distance between data points meets the threshold is used as the first area, or the area where the clustering / classification result meets the threshold is used as the first area, etc., which is not unique specifically. After determining the first area, the device can perform a fisheye distortion transformation on the first area to form a second area with a display state different from that of the first area. In this second area, each data point is still displayed in the form of a data point, but the display position of each data point and the display form of each data point, etc. can be different from the position and display form in the first area. After completing the area conversion, determine the display position of each data point in the second area, then obtain the specific data information corresponding to each data point in the second area, such as the data graph, and finally display the corresponding data graph at the display position of each data point.

[0058] Based on the disclosure of the above embodiments, the beneficial effects of this embodiment include determining the first area in the scatter plot of the data set, performing a fisheye distortion transformation on the first area to form a second area with a display state different from that of the first area, then determining the display position of each data point in the second area, obtaining the data graph of each data point in the second area, and finally displaying the corresponding data graph based on the display position of each data point. In this way, not only can the data graphs of each data point in the second area be clearly displayed for the user, but also the system will not crash due to excessive load. At the same time, since the data graphs of each data point in the second area can be displayed, it can assist the user to better observe the overall clustering / classification situation of the data set, the characteristic distances between various types of data, the characteristic distances between data within the class, etc., and can assist the user to quickly judge the clustering / classification of the data and the advantages and disadvantages of the dimensionality reduction algorithm, and quickly detect and locate incorrect clustering / classification data.

[0059] Further, in this embodiment, determining the first area in the scatter plot of the data set includes:

[0060] In response to an instruction, determine a first region based on the position of an indication icon in a scatter plot of a data set, where the indication icon is controlled by a user to move via an input device.

[0061] Suppose a user uses an electronic device to open a scatter plot of a data set and displays it using a display device. When the user wants to view the data plot in a certain region of the scatter plot of the data set, the user can use the input device of the electronic device, such as a mouse, a keyboard, an electronic pen, etc., to control the movement of the indication icon on the display device to determine the first region through the indication icon. For example, when the user moves the mouse to make the indication icon located in the region that the user wants to view and then stops moving, the user can click the left mouse button in this region to send an instruction to the electronic device to confirm that this region is the first region, or the user can control the indication icon to stay in this region for 1 s - 5 s, and at this time the electronic device will automatically generate a confirmation instruction. Or, as the indication icon moves on the scatter plot of the data set, the first region is determined in real time and a confirmation instruction is generated in real time, that is, when the position of the indication icon changes, the first region also changes. When the electronic device obtains the confirmation instruction, it will respond to this instruction and determine the first region based on the position of the indication icon in the scatter plot of the data set. The first region can be comprehensively determined based on the size parameters pre-set by the user in combination with the position where the indication icon is located, or based on the default size parameters in combination with the position where the indication icon is located, or can also be comprehensively determined based on the size parameters input by the current user and in combination with the position where the indication icon is located. The above size parameters can be, for example, radius and diameter parameters. The first region is a circular region with the position where the indication icon is located as the center and the above radius and diameter parameters as the radius or diameter. Of course, the size parameter can also be an area parameter, and the first region can also be a square region. The corresponding size parameters can be the side lengths of the square region, and the position where the indication icon is located can be the center of the square region, etc. In this embodiment, it is preferred that the first region is a circular region to facilitate the subsequent fisheye conversion operation.

[0062] Further, in this embodiment, when determining the first region based on the position of the indication icon in the scatter plot of the data set, it includes:

[0063] Obtain a distortion radius;

[0064] Take the current position of the indication icon as the center point and determine the first region based on the center point and the distortion radius.

[0065] Continuing to combine the above embodiment, when the user controls the indication icon to be located at a certain position on the scatter plot of the data set through the manipulation of the input device and generates a confirmation instruction, such as Figure 4As shown, the electronic device obtains a distortion radius, which can be pre-set by the user and stored in the electronic device, or can be a parameter currently input by the user, or can be a default parameter in an application program for implementing fisheye transformation. The specific obtaining method is not unique. In addition, the distortion radius can also be changed according to the user's instruction or the different positions of the current indication icon. For example, the default distortion radius is 5, and the user can increase the distortion radius to 8 by inputting an instruction indicating an increase in the distortion radius, or for different positions of the corresponding indication icon, the corresponding distortion radius is also different. For example, for different regions of the scatter plot of the data set, the set distortion radii are different. The electronic device can determine the distortion radius matching the position of the indication icon according to which region the current position of the indication icon is located in. After the electronic device obtains the distortion radius, it determines the current position of the indication icon, and takes this current position as the center point, and determines a circular area with the obtained distortion radius as the radius, and determines this circular area as the first area.

[0066] In addition, in this embodiment, when determining the first area, the following method can also be used for determination:

[0067] Assist in determining the first area based on one or more of scaling, roaming, and navigation of the scatter plot of the data set.

[0068] For example, the user can combine one or more of scaling, roaming the scatter plot of the data set, or navigating based on a certain keyword to find the area he wants to view, and input a determination instruction through the input device to make the electronic device determine the first area that meets the user's viewing requirements.

[0069] Further, after determining the first area, when performing fisheye distortion transformation on the first area to form the second area in this embodiment, it includes:

[0070] Obtain the fisheye distortion degree;

[0071] Perform fisheye distortion transformation on the first area based on the fisheye distortion degree to form the second area.

[0072] For example, after determining the first region in this embodiment, the electronic device obtains the fisheye distortion. The fisheye distortion can be set by the user in advance and stored in the electronic device, or can be a parameter currently input by the user, or can be the default parameter in the application program that implements the fisheye transformation. The specific obtaining method is not unique. In addition, the fisheye distortion can be a fixed parameter or a variable parameter. For example, it can be changed proportionally according to the distortion radius and the size of the first region, or can be changed accordingly according to the density and quantity of the data points in the current first region. For example, if there are many data points, the distortion is large; if there are few data points, the distortion is small; or if there are many data points, the distortion is small, etc. It can also be changed according to the position of the first region. For example, for different positions where the first region is located, the fisheye distortion is different, etc. Moreover, the above fisheye distortion can be the fisheye distortion corresponding to all the data points in the first region, that is, only one value of the fisheye distortion is obtained, or multiple values can be obtained, that is, multiple fisheye distortions are obtained. For example, there can be different fisheye distortions corresponding to different positions in the first region, or even the fisheye distortions corresponding to the data points at different positions in the first region. After obtaining the above fisheye distortion, the electronic device determines the first region and the data points therein. For example, it determines which data points need to be distorted and which do not, determines the boundary for the data point distortion transformation (i.e., the boundary of the first region), and then, after determining that the boundary is within the distortion radius, only distorts the data points within the boundary, while the data points outside the boundary are still displayed in their original state. That is, based on the fisheye distortion, a fisheye distortion transformation is performed on the first region of the data scatter plot. When specifically performing the distortion transformation operation, the electronic device calculates and determines the distortion degree of each data point in the first region based on the obtained fisheye distortion, and then distorts the data points in the first region based on the distortion degree of each data point, and at the same time changes the positions of each data point or the data points that need to be changed (for example, for some data points, their positions may remain unchanged after the fisheye distortion transformation, and such data points are the data points that do not need to change their positions), thereby forming a second region from the first region.

[0073] Further, when determining the display position of each data point in the second region in this embodiment, it includes:

[0074] Calculating and determining the display position of each data point in the second region based on the current position of the indication icon, and the display position of each data point is determined by the distance between each data point and the current position of the indication icon.

[0075] In this embodiment, the positions of the data points in the second region are not fixed, but can change accordingly as the indicator icon moves. However, each change does not necessarily involve the positions of all the data points in the second region changing. It can be that all the data points change, or only the positions of some of the data points change. Specifically, after the formation of the second region in this embodiment, the position of the current indicator icon is determined, and this current position is determined as the central position. Then, based on this central position, the display positions of each data point in the second region are calculated and determined. The display position of each data point is determined by the distance between each data point and the central position. For example, after the fisheye distortion transformation, the positions of the data points are arranged in a state where the farther away from the central position, the denser they are. That is, the display area at the central position is the largest and the number of data points is the least. The closer to the boundary of the second region, the denser the data points and the smaller the display area. Or, it can also be that starting from the central position, the data points are distributed in a scattered manner outward, and the distances between the display positions of the data points increase proportionally, and they can even be the same. However, it should be noted that when the central position changes, the display positions of the remaining data points also change accordingly.

[0076] Furthermore, when calculating and determining the display positions of each data point in the second region based on the current position of the indicator icon in this embodiment, it includes:

[0077] Determine the distance value between each data point and the current position of the indicator icon;

[0078] Based on the distance corresponding to each data point, determine the minimum distance value;

[0079] Determine that the display position of the data point corresponding to the minimum distance value is located in the central region of the second region, and arrange the display positions of the remaining data points in sequence along the direction away from the central region according to the rule of increasing distance values.

[0080] For example, when determining the display positions of respective data points in this embodiment, the distance values between each data point in the second region and the current position of the indication icon are first determined. Then, based on the distances corresponding to each data point, the minimum distance value is determined, that is, the data point closest to the indication icon. For example, a data point located beside the indication icon, or it could also be the data point indicated by the indication icon, that is, the indication icon is located on the data point, which is equivalent to having a distance of 0 from the indication icon. Next, it is determined that the display position of the data point closest to the indication icon is in the central region of the second region, that is, displayed in the center region of the circle. The display positions of the remaining data points are then arranged in sequence along the direction away from the central region / center region of the circle according to the rule of increasing distance values. Specifically, for the layout position, the central region can be a region in the shape of a circle or a square, etc. There are multiple data points in the central region, and correspondingly, there are also multiple data graphs displayed in this central region. The data point at the center of the central region is the data point closest to the position of the indication icon, and the display position of the data graph corresponding to this data point is at this center. For the remaining data points, they can be distributed with multiple data points at equal distances based on the distance values, or they can be arranged with multiple data points based on a distance trend inversely proportional to the distance values. For example, the smaller the distance value, the greater the distance between two adjacent data points, and it is necessary to move them to the positions of the data points farther from the central region to increase their distances from the data points in the central region to provide space for the display of the data graphs of the data points in the central region. For the remaining data points with large distance values, they gradually approach the edge region of the second region, and the distance between two adjacent data points is smaller. Or, it can also be based on the distance values for region division, such that the data points with distance values within the first threshold range are distributed in the first annular region centered on the central region. This first annular region is the annular region closest to the central region. The data points with distance values within the second threshold range are distributed in the second annular region also centered on the central region. The radius of this second annular region is greater than the radius of the first annular region. Subsequently, a third threshold range, a fourth threshold range, etc. can also be set. The data points within the third threshold range and the fourth threshold range are respectively located in the third annular region and the fourth annular region, and the radius of the fourth annular region is greater than the radius of the third annular region, and the radius of the third annular region is greater than the radius of the fourth annular region. Moreover, the number of data points in the fourth annular region can be the largest, that is, the closer to the edge region of the second region, the more data points there are in the annular region. In the direction gradually approaching the central region, the number of data points in each annular region can decrease in sequence. Of course, the number of data points can also remain unchanged, or only the number of data points in certain annular regions is more, etc. When the position of the indication icon changes, since the current positions of each data point and the indication icon change, the positions of all data points need to be recalculated, and even the first region needs to be re-determined.

[0081] Further, the method in this embodiment further includes:

[0082] Calculate the distortion degree based on the display position of each data point, and multiple data points are discretely displayed in the second area based on the corresponding distortion degrees.

[0083] For example, after determining the display position of each data point, the electronic device calculates the distortion degree corresponding to each data point based on the display position of each data point. If the previously obtained fisheye distortion degrees include the distortion degrees of each data point, this step can be ignored; otherwise, calculation is required to determine. The calculation of the distortion degree can be based on the specific display position where the data point is located or the area where the display position is located. In the second area, for different areas, the distortion degrees of the data points are different, that is, the distortion degrees of the data points located in the same area are the same, and the distortion degrees of the data points in different areas are different. The area mentioned above can be the annular area described above, or an area set by the user, or different fan-shaped areas, etc. In this embodiment, for the area closest to the central area, the distortion degree of the internal data points is the smallest; the farther the area is from the central area, the greater the distortion degree of the internal data points, that is, the distortion degree of the data points changes in a gradual trend. Of course, this rule is not unique. It can also be that for the area closest to the central area, the distortion degree of the data points in this area is the smallest; for the area farthest from the central area, the distortion degree of the data in this area is the largest, and for the areas between the two, the distortion degrees of the data points can be the same. After determining the distortion degrees of each data point, the electronic device displays each data point in a discrete form in the second area based on each distortion degree, and the display state of each data point matches the corresponding distortion degree.

[0084] Specifically, when displaying the corresponding data graph based on the display position of each data point in this embodiment, it includes:

[0085] Process the data graph of each data point based on the distortion degree corresponding to each data point;

[0086] Display the processed data graph based on the display position of the corresponding data point. Among them, the display size of the data graph at the display position located in the central area of the second area is the largest, and the display sizes of the data graphs at the remaining display positions gradually decrease in the direction away from the central area.

[0087] For example, as Figure 6 and Figure 7As shown, after the electronic device determines the display positions of each data point and the distortion degree of each data point, it will obtain the data graph corresponding to each data point, and then process the data graph of each data point based on the distortion degree of each data point. After processing the data graph, the electronic device will display the matching data graph based on the display positions of each data point in the previously determined second region. For different display positions, the display effects of each data graph are not fixed. Among them, for the display positions of each data point, the display size of the data graph located in the above-mentioned central region is the largest, and for the data points at the remaining display positions, the farther away from the central region, the smaller the display size of the data graph. Or, continuing from the previous embodiment, the display size of the data graph in the annular region closest to the central region is larger than that of the data graph in the next adjacent annular region, and so on. For the data graphs located in the same annular region, the display sizes are the same, or for the data graphs located in the same annular region, the closer to the central region, the larger the display size, and the specific display method is uncertain. As the user moves the indication icon in the second region, the data graph located in the central region can be different. The specific data can be selected by the user moving the indication icon, or the user first inputs an instruction that does not change the second region and does not require re-determining the first region, and then moves the indication icon in the second region to select the data graph to be enlarged and displayed in the central region. For example, the user moves the indication icon on the basis of Figure 6 so that the electronic device changes the data graph displayed in the central region, forming a state as shown in Figure 7 . The data graphs at other positions may be partially blocked between data graphs due to limited display space, but cannot be completely blocked. In addition, for the data graphs displayed in the central region or other display positions, the user can, for example, double-click and other operations to make the selected data graph full-screen display, or the user can also perform zoom adjustment on the selected data graph through zoom operations. Further, based on the displayed data graph, the user can perform visual analysis on the data set scatter plot, and perform clustering and classification on multiple data points based on the specific content of the displayed data graph. For example, the data graph with a person is divided into one category, or the data graph with a specified person is divided into one category, or it can also be classified according to the shooting time, download time, and upload time of the data graph, etc. Of course, in specific applications, it is not limited to the above classification operations, and other visual analysis and processing can also be performed on the data points based on the displayed data graph.

[0092] An acquisition module for acquiring the data graph of each data point in the second region;
