[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0049] The following is combined with Figures 1-9 The present invention describes a graph generation method, a graph generation apparatus, and an electronic device.

[0050] The curve generation method of this invention includes steps 110, 120, 130 and 140.

[0051] Step 110: Obtain the display width and display height of the display device.

[0052] It is understandable that a display device is a container used to display graphs, and different display devices have different sizes and different aspect ratios.

[0053] The display width of a display device is the width of the area within the display device that can be used for display and presentation, and the display height of a display device is the height of the area within the display device that can be used for display and presentation.

[0054] The display device can be a screen, monitor, television, large display screen, or other similar device of an electronic device; there is no restriction on the type of display device.

[0055] Step 120: Determine the first coefficient based on the display width and the first target dataset, and determine the second coefficient based on the display height and the second target dataset.

[0056] It should be noted that the first target dataset is the dataset corresponding to the horizontal axis, and the second target dataset is the dataset corresponding to the vertical axis.

[0057] When plotting curves based on different data, the meanings of the parameters represented by the horizontal and vertical axes of the curves will also be different.

[0058] For example, when plotting a train distance-time (ST) curve, the first target dataset is the dataset corresponding to time T on the horizontal axis, and the second target dataset is the dataset corresponding to distance S on the vertical axis.

[0059] When plotting the speed-distance (VS) curve of a train, the first target dataset is the dataset corresponding to the distance S on the horizontal axis, and the second target dataset is the dataset corresponding to the speed V on the vertical axis.

[0060] It is understandable that the horizontal axis of the display device is used to draw the curve along the display width direction, and the vertical axis of the display device is used to draw the curve along the display height direction.

[0061] Based on the display width and the first target dataset, a first coefficient can be determined, which is used to characterize the relationship between the horizontal axis of the curve and the display width of the display device.

[0062] Based on the display height and the second target dataset, a second coefficient can be determined, which is used to characterize the relationship between the vertical axis of the curve and the display height of the display device.

[0063] In some embodiments, determining a first coefficient based on the display width and a first target dataset includes obtaining the distance X1 from the left boundary of the display device and the distance X2 from the right boundary of the display device to the curve display area in the display device.

[0064] Understandably, graphs are used to display data within the area of ​​a display device that is available for display and presentation. However, the area displayed by a graph is smaller than the area available for display and presentation on the display device.

[0065] After determining the distances X1 from the left boundary of the curve display area to the right boundary of the display device, X2 from the right boundary of the display device, Y1 from the top boundary of the display device, and Y2 from the bottom boundary of the display device, the first coefficient and the second coefficient can be confirmed.

[0066] In some embodiments, the maximum value M in the first target dataset can be used as the basis. objmax Determine the first coefficient.

[0067] It is understandable that the maximum value in the first target dataset represents the maximum value of the data corresponding to the horizontal axis in the curve graph.

[0068] In this embodiment, the first coefficient K1 = (ScreenWidth - X1 - X2) / (MaxX * ScaleX).

[0069] ScreenWidth represents the display width of the display device, and the width of the area in the display device that can be used for display is ScreenWidth-X1-X2.

[0070] In some embodiments, X1 = X2 = 0.1 * ScreenWidth. Of course, X1 and X2 can also be other values, such as 0.2 * ScreenWidth. X1 and X2 can be equal or unequal. There are no restrictions on the values ​​of X1 and X2 here.

[0071] MaxX is used to represent the fixed scaling factor and maximum value M of the horizontal axis. objmax The product of the products can have a fixed proportionality coefficient that can be any value between 1 and 2, such as 1.1. There is no restriction on the value of the fixed proportionality coefficient here.

[0072] ScaleX is used to represent the initial scaling factor of the horizontal axis, reflecting the user's scaling factor in the horizontal axis direction of the curve. The default value of ScaleX can be 1.

[0073] In some implementation examples, the second coefficient is determined based on the display height and the second target dataset, including: obtaining the distance Y1 from the upper boundary of the display device and the distance Y2 from the lower boundary of the display device to the curve display area in the display device.

[0074] In some embodiments, the maximum value M in the second target dataset can be used as the basis. objmax Determine the second coefficient.

[0075] It is understandable that the maximum value in the second target dataset represents the maximum value of the data corresponding to the vertical axis in the curve graph.

[0076] In this embodiment, the second coefficient K2 = (ScreenHeight - Y1 - Y2) / (MaxY * ScaleY).

[0077] ScreenHeight represents the display height of the display device, and the height of the area in the display device that can be used for display is ScreenHeight-Y1-Y2.

[0078] In some embodiments, Y1 = Y2 = 0.1 * ScreenHeight. Of course, Y1 and Y2 can also be other values, such as 0.2 * ScreenHeight. Y1 and Y2 can be equal or unequal. There are no restrictions on the values ​​of Y1 and Y2 here.

[0079] MaxY is used to represent the fixed scaling factor and maximum value N of the ordinate. objmax The product of the products can have a fixed proportionality coefficient that can be any value between 1 and 2, such as 1.1. There is no restriction on the value of the fixed proportionality coefficient here.

[0080] ScaleY is used to represent the initial scaling factor of the vertical axis, reflecting the scaling factor applied by the user to the vertical axis of the curve. The default value of ScaleY can be 1.

[0081] According to the curve generation method of the present invention, a first coefficient and a second coefficient are determined based on the maximum value in the dataset of the generated curve and the size of the area in the display device that can be used for display and presentation, taking into account the user's scaling requirements, thereby realizing the transformation from the dataset to the coordinate curve graph. This method can take into account the size of the actual display area of ​​the display device, the characteristics of the data, and the user's needs, so that the curve graph can better meet the user's needs.

[0082] Step 130: Based on the first coefficient and the first target dataset, determine the displayed abscissa X = K1 * M of the target point according to the formula for determining the displayed abscissa. obj +L1, based on the second coefficient and the second target dataset, determine the displayed ordinate Y of the target point according to the formula for determining the displayed ordinate Y = K2 * N. obj +L2.

[0083] It is understandable that the target points are the points on the graph corresponding to two data points in the first and second target datasets. K1 is used to represent the first coefficient, and K2 is used to represent the second coefficient.

[0084] M obj N represents the original data corresponding to the x-coordinate of the target point in the first target dataset. obj The ordinate of the target point corresponds to the original data in the second target dataset.

[0085] For example, when plotting a train distance-time (ST) curve, M obj For data at time T, N obj This is the data for distance S.

[0086] When plotting the speed-distance (VS) curve of a train, M obj For the distance S, N obj The data is for time T.

[0087] L1 represents the offset of the target point's x-coordinate, and L2 represents the offset of the target point's y-coordinate.

[0088] It should be noted that the initial values ​​of L1 and L2 can be 0. In this case, the value of L1 and L2 is 0 to indicate that the user has not dragged the graph. When the graph is displayed on the display device, the coordinate points corresponding to all data in the first target dataset and the second target dataset can be displayed and viewed on the display device.

[0089] Step 140: Generate the target curve based on the displayed horizontal and vertical axes.

[0090] It is understandable that the displayed horizontal and vertical coordinates are coordinates on the display device, and the displayed horizontal and vertical coordinates correspond to the positions in the width and height directions of the display device, respectively.

[0091] After determining the distances X1 from the left boundary of the graph display area to the right boundary of the display device, X2 from the right boundary of the display device, Y1 from the top boundary of the display device, and Y2 from the bottom boundary of the display device, the positions of the coordinate axes can be determined.

[0092] For example, when the data in both the first and second target datasets are positive, the target points are all located in the first quadrant. The distance between the origin of the curve and the left boundary of the display device is X1, and the distance between the origin of the curve and the lower boundary of the display device is Y2.

[0093] The curves in the display device can be obtained from multiple target points through fitting, regression, and other methods.

[0094] The graph generation method according to embodiments of the present invention generates graphs that are adapted to different types of data, different sizes of display devices, and user operation needs by combining data characteristics, display device size, user scaling and dragging requirements, thereby improving the display and presentation effect, better meeting user needs, and facilitating user inspection and analysis of data.

[0095] In some embodiments, such as Figure 2As shown, after generating the target curve based on the first dataset and the second dataset, the curve generation method further includes: receiving input from the user through mouse wheel scrolling and obtaining the display coordinates (X', Y') of the mouse point.

[0096] Understandably, after generating the graph, the data can be checked and analyzed based on the graph.

[0097] In this embodiment, control commands can be input using a mouse.

[0098] Each time the mouse wheel is scrolled, the direction of the scrolling and the display coordinates of the mouse point on the display device are obtained.

[0099] The scaling factor K3 can be determined based on the scrolling direction of the mouse wheel.

[0100] In some embodiments, when the mouse wheel scrolling direction is a first direction, the scaling factor K3 satisfies 0 < K3 < 1. For example, the value of K3 can be 0.875.

[0101] When the mouse wheel scrolls in the second direction, the scaling factor K3 must be greater than 1. For example, the value of K3 can be 1.125.

[0102] It should be noted that the first direction and the second direction are opposite directions.

[0103] In some embodiments, the product of the two scaling factors can be 1 in two different scrolling directions of the mouse wheel, so that the visual difference between a single zoom-out and a single zoom-in is the same, making it easy for the user to undo the previous zoom operation by scrolling the mouse wheel in the opposite direction.

[0104] For example, when the first direction is upward, after detecting the signal of the mouse wheel scrolling upward, it can be determined that an instruction to zoom in on the curve needs to be executed.

[0105] In this case, the second direction is downward. After detecting the signal of the mouse wheel scrolling downward, it can be determined that an instruction to shrink the curve needs to be executed.

[0106] After determining the scaling factor, the first target factor, the second target factor, the offset of the horizontal axis, and the offset of the vertical axis are re-determined based on the scaling factor and the display coordinates of the mouse point.

[0107] In this embodiment, the first target coefficient K1' = K1 * K3 is redefined, and the second target coefficient K2' = K2 * K3 is redefined.

[0108] Based on the formulas for determining the horizontal and vertical coordinates, the offset of the redefined horizontal coordinate is L1' = X' - K1' * M. obj The offset of the redefined ordinate L2' = Y' - K2' * N obj This allows for the updating of parameters in the formulas for determining the horizontal and vertical coordinates.

[0109] Based on the newly determined formulas for determining the horizontal and vertical coordinates, the horizontal and vertical coordinates are redefined, and then the target curve is regenerated based on the horizontal and vertical coordinates.

[0110] like Figure 3 and Figure 4 As shown, Figure 3 The horizontal axis represents time T, and the vertical axis represents velocity V. When the user moves the mouse point to the area on the left side of the curve in the graph and scrolls the mouse wheel upwards, Figure 3 The curve in the image is magnified to obtain Figure 4 The curve. Accordingly, the coordinates in the coordinate system of the display device can also be updated accordingly.

[0111] According to the curve graph generation method of the present invention, by receiving the user's scrolling operation of the mouse wheel, the corresponding position in the curve graph can be scaled, which makes it convenient for the user to view on the display device and can better meet the user's needs.

[0112] In some embodiments, refer to Figure 5 After generating the target curve, the curve generation method also includes receiving user input via mouse clicks and drags, and obtaining the display coordinates (X, Y, F, Z) of the mouse point during the dragging process. t Y t ).

[0113] It is understandable that the graph is moved by clicking the mouse and during the clicking process.

[0114] When the mouse click is released, the offsets of the horizontal and vertical axes are redefined. The redefined horizontal offset L1' = X. t -K1*M obj The offset of the redefined ordinate L2' = Y t -K2*N obj .

[0115] After updating the parameters in the formulas for determining the horizontal and vertical coordinates, the horizontal and vertical coordinates are redefined, and the target curve is regenerated based on the horizontal and vertical coordinates.

[0116] like Figure 3 and Figure 6 As shown, when the user presses the mouse and moves the mouse point located in the center of the graph upwards, Figure 3 The curve in the middle is moved to obtain Figure 6 The curve in the display device. Correspondingly, the coordinates in the coordinate system of the display device can also be updated accordingly.

[0117] According to the curve generation method of the present invention, by receiving the user's drag operation with the mouse, the curve in the curve graph can be moved, making it convenient for the user to view the data at the target position on the display device, and can better meet the user's needs.

[0118] In some embodiments, such as Figure 7 As shown, after obtaining the first coefficient and the second coefficient based on the first dataset and the second dataset, the display coordinates of the target point on the display device can be obtained, and the target curve can be generated.

[0119] After receiving the user's zoom and drag input, the system can reconfirm the first coefficient, the second coefficient, and the offset of the horizontal and vertical axes based on the user's input.

[0120] User zooming and dragging input can also be done through touch input, voice input, key input, etc.

[0121] In this embodiment, by combining the characteristics of the data, the size of the display device, and the user's scaling and dragging needs, a graph is generated that is adapted to different types of data, different sizes of display devices, and user operation needs, so that the display and presentation effect is better, more in line with the user's needs, and easier for the user to check and analyze the data.

[0122] The curve generation apparatus provided by the present invention will be described below. The curve generation apparatus described below can be referred to in correspondence with the curve generation method described above.

[0123] Reference Figure 8 The graph generation device of this invention includes an acquisition module 810, a first processing module 820, a second processing module 830, and a generation module 840.

[0124] The acquisition module 810 is used to acquire the display width and display height of the display device;

[0125] The first processing module 820 is used to determine a first coefficient based on the display width and the first target dataset, and to determine a second coefficient based on the display height and the second target dataset, wherein the first target dataset is the dataset corresponding to the horizontal axis and the second target dataset is the dataset corresponding to the vertical axis.

[0126] The second processing module 830 is used to determine the display x-coordinate X = K1*M of the target point based on the first coefficient and the first target dataset. obj +L1, based on the second coefficient and the second target dataset, determine the displayed ordinate Y = K2*N of the target point. obj +L2, K1 is used to represent the first coefficient, K2 is used to represent the second coefficient, M obj N represents the original data corresponding to the x-coordinate of the target point in the first target dataset. obj L1 represents the original data corresponding to the ordinate of the target point in the second target dataset, and L2 represents the offset of the x-coordinate of the target point.

[0127] The generation module 840 is used to generate a target curve based on the displayed horizontal and vertical coordinates.

[0128] According to an embodiment of the present invention, a graph generation device combines data characteristics, display device size, user scaling and dragging needs to generate graphs that are suitable for different types of data, display devices of different sizes, and user operation needs, resulting in better display and presentation effects, better meeting user needs, and facilitating user inspection and analysis of data.

[0129] In some embodiments, the first processing module is further configured to obtain the distance X1 from the left boundary of the display device and the distance X2 from the right boundary of the display device to the curve display area in the display device; based on the maximum value M in the first target dataset... objmax Determine the first coefficient K1 = (ScreenWidth - X1 - X2) / (MaxX * ScaleX); where ScreenWidth represents the display width, and MaxX represents the fixed scaling factor of the horizontal axis and its maximum value M. objmax The product of ScaleX and ScaleX represents the initial scaling factor of the horizontal axis.

[0130] In some embodiments, the first processing module is further configured to obtain the distance Y1 from the upper boundary of the display device and the distance Y2 from the lower boundary of the display device to the curve display area in the display device; based on the maximum value N in the second target dataset... objmax The second coefficient K2 is determined as K2 = (ScreenHeight - Y1 - Y2) / (MaxY * ScaleY); where ScreenHeight represents the display height, and MaxY represents the fixed scaling factor of the vertical axis and its maximum value N. objmax The product of ScaleY and ScaleY is used to represent the initial scaling factor of the ordinate.

[0131] In some embodiments, the graph generation apparatus of the present invention further includes a third processing module, which is used to receive input from a user via a mouse wheel scrolling operation and obtain the display coordinates (X', Y') of the mouse point; determine a scaling factor K3 based on the scrolling direction of the mouse wheel; and redetermine a first target factor, a second target factor, an offset of the horizontal axis, and an offset of the vertical axis based on the scaling factor and the display coordinates of the mouse point. The redetermined first target factor K1' = K1 * K3, the redetermined second target factor K2' = K2 * K3, and the redetermined offset of the horizontal axis L1' = X' - K1' * M obj The offset of the redefined ordinate L2' = Y' - K2' * N obj ; Redefine the displayed x-axis and y-axis; Based on the displayed x-axis and y-axis, regenerate the target curve.

[0132] In some embodiments, when the mouse wheel scrolling direction is a first direction, the scaling factor K3 satisfies 0 < K3 < 1; when the mouse wheel scrolling direction is a second direction, the scaling factor K3 satisfies K3 > 1; wherein the first direction and the second direction are opposite directions.

Figure 9As shown, the electronic device may include: a processor 910, a communication interface 920, a memory 830, and a communication bus 940, wherein the processor 810, the communication interface 920, and the memory 930 communicate with each other through the communication bus 940. The processor 910 can call logical instructions in the memory 930 to execute a curve generation method, which includes: obtaining the display width and display height of the display device; determining a first coefficient based on the display width and a first target dataset; determining a second coefficient based on the display height and a second target dataset, wherein the first target dataset is the dataset corresponding to the horizontal axis, and the second target dataset is the dataset corresponding to the vertical axis; and determining the display horizontal coordinate X = K1*M of the target point based on the first coefficient and the first target dataset. obj +L1, based on the second coefficient and the second target dataset, determine the displayed ordinate Y = K2*N of the target point. obj +L2, K1 is used to represent the first coefficient, K2 is used to represent the second coefficient, M obj N represents the original data corresponding to the x-coordinate of the target point in the first target dataset. obj The target point's ordinate is the original data corresponding to the target point's x-coordinate in the second target dataset.
