[0040] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions of the embodiments of this specification will be clearly and completely described below in conjunction with the drawings of the embodiments of this specification. Obviously, the embodiments described in this specification are only some embodiments of this application, not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0041] In the prior art, heat map is a commonly used data display method. However, the existing heat map generation technology requires users to access real data and generate heat maps based on real data, which has problems such as slow generation speed, high machine resource usage, and low generation efficiency.

[0042] The first embodiment of this specification (hereinafter referred to as "embodiment one") provides a data display method. The execution subject of embodiment one can be a terminal (including but not limited to mobile phones, computers, pads, televisions) or a server or an operating system or an application or a data display platform or a data display system, etc., that is, the execution subject can be various and can be set, used or changed as needed. In addition, a third-party application can also assist the execution subject in executing embodiment one. For example Figure 1As shown, the data display method in Example 1 can be executed by a server, and an application corresponding to the server can be installed on a terminal (held by a user). Data can be transmitted between the terminal or the application and the server, and data can be collected, input or output, or pages or information processing can be performed (to the user) through the terminal or the application, thereby assisting the server in executing the data display method in Example 1.

[0043] like Figure 2 As shown, the data display method provided in the first embodiment includes:

[0044] S101: (Executing body) obtaining a screen target point on the display screen, and determining a map target point in the map corresponding to the screen target point; wherein the map target point is a first group of data points;

[0045] The execution subject of the first embodiment may have a display screen, and the user may select on the display screen by means of a mouse, keyboard, or touch. Among them, the execution subject of the first embodiment may determine the user's positioning point on the display screen according to the mouse operation, screen touch operation, or keyboard operation, and the positioning point may be referred to as the screen target point. For example, the execution subject of the first embodiment may use the mouse click point, touch point, or point pointed to by keyboard operation (for example, the cursor position is manipulated by the keyboard direction keys, and the position is selected by the enter key, and the selected position is the pointed point) as the screen target point.

[0046] In the first embodiment, the execution body of the first embodiment can display a map, and the user can select the screen target point on the map, and the execution body of the first embodiment determines the map target point in the map corresponding to the screen target point. Wherein, determining the map target point in the map corresponding to the screen target point may include: determining the screen coordinates of the screen target point (i.e., the coordinates in the screen), converting the screen coordinates of the screen target point into a three-dimensional ray using a projection matrix, and determining the intersection point of the three-dimensional ray and the map in the screen, wherein the intersection point is the map target point corresponding to the screen target point. The execution body of the first embodiment can determine the coordinates of the map target point in the map (i.e., the world coordinates, which may be three-dimensional coordinates).

[0047] The execution subject of the first embodiment may determine the map target point as the first group of data points, such as Figure 3 shown.

[0048] S103: (Executing body) construct 3 with the nth group of data points as the center n ×3 n Level data array, the 3 n ×3 n The level data array is taken as the n+1th group of data points; wherein n≥1;

[0049] The execution subject of the first embodiment can perform data diffusion in the following manner:

[0050] As described above, the map target point is the first group of data, and the execution body of the first embodiment can construct a 3×3 level data array, that is, a data array with 3 rows and 3 columns, with the first group of data points as the center. The 3×3 level data array is the second group of data points, such as Figure 4 shown.

[0051] The execution body of the first embodiment can construct a 9×9 level data array, that is, a data array with 9 rows and 9 columns, with the second group of data points as the center. The 9×9 level data array is the third group of data points, such as Figure 5 shown.

[0052] The execution body of the first embodiment can construct a 27×27 level data array, ie, a data array of 27 rows and 27 columns, with the third group of data points as the center. The 27×27 level data array is the fourth group of data points.

[0053] And so on.

[0054] The execution body of the first embodiment can construct 3 with the nth group of data points as the center. n ×3 n Level data array, i.e. 3 n Row 3 n The data array of the columns is n ×3 n The level data array is the n+1th group of data points, where n≥1, the same below.

[0055] In the first embodiment, the distance between adjacent data points in each row of each data array is the same, the distance between adjacent data points in each column is the same, and the distance between adjacent data points in each row is the same as the distance between adjacent data points in each column. That is to say, for any data array, the four data points corresponding to the four intersections of any two adjacent rows and any two adjacent columns of the data array are equivalent to the four vertices of a square, and the side length of the square is the distance between adjacent data points in each row of the data array, that is, the distance between adjacent data points in each column of the data array, such as Figure 5 It should be noted that Figures 3 to 5 In order to make it clear, the area of ​​a single data point is larger. In actual scenarios, data points only exist as points. Data points may not have the concept of area, and the distance between adjacent data points has nothing to do with the area of ​​the points.

[0056] In the first embodiment, the nth group of data points is taken as the center to construct 3 n ×3 nThe level data array may include: taking the nth group of data points as the center, constructing diffuse data points around the nth group of data points, the diffuse data points together with the nth group of data points forming a 3 n ×3 n The diffusion data points are composed of 8 data arrays, each of which is the same as the nth group of data, that is, each data array is 3 n-1 ×3 n-1 Level data array.

[0057] In the following, each data array identical to the nth group of data among the diffusion data points constructed around the nth group of data points with the nth group of data points as the center is referred to as the diffusion data group of the nth group of data.

[0058] For the nth group of data points, the intersection of the middle row and the middle column is the center point of the nth group of data points, that is, the (3 n-1 +1) / 2 and (3 n-1 +1) / 2 columns is the center point of the nth group of data points. In the first embodiment, the center point of each group of data points is the map target point.

[0059] In the first embodiment, each diffusion data group of the nth group of data has its center point, so the 8 diffusion data groups of the nth group of data have 8 center points. The center points of the 8 diffusion data groups of the nth group of data are respectively located on the positive and negative semi-axes of the horizontal coordinate, the positive and negative semi-axes of the vertical coordinate, and the bisectors of the four quadrants of the coordinate axis with the map target point as the origin.

[0060] That is to say, the nth group of data is regarded as a data group, and the 8 diffusion data groups of the nth group of data can be regarded as data groups after the nth group of data is offset along 8 directions, respectively, and the 8 directions are the positive direction and negative direction of the horizontal coordinate of the coordinate axis with the map target point as the origin, the positive direction and negative direction of the vertical coordinate, and the directions of the bisectors of the four quadrants of the coordinate axis. In the first embodiment, these 8 directions can be called data diffusion directions.

[0061] From the above, we can see that the second group of data points is diffused with the first group of data points as the center, the third group of data points is diffused with the second group of data points as the center, and so on, the n+1th group of data points is diffused with the nth group of data points as the center. This diffusion method can also be called step-by-step diffusion.

[0062] Although the eight diffusion data groups of the nth group of data can be regarded as data groups obtained by respectively shifting the nth group of data along eight data diffusion directions, each diffusion data group of the nth group of data is not obtained by shifting the nth group of data along a certain data diffusion direction. In fact, the generation method of each diffusion data group of the nth group of data is the same as the generation method of the nth group of data points, that is, each diffusion data group of the nth group of data is also generated by the same data diffusion method as the nth group of data points. In other words, the generation method of each diffusion data group of the nth group of data is: determine the center point of the diffusion data group, and obtain the diffusion data group from the center point through step-by-step diffusion.

[0063] S105: (Execution entity) When a group of data points contains a certain number of data points that meets the standard, the color of each data point in the group of data points that meets the standard is drawn according to the distance between each data point in the group of data points that meets the standard and the target point of the map, so as to generate a heat map of the area corresponding to the group of data points that meets the standard; or, when a group of data points contains a certain number of data points that meets the standard, the data value of each data point in the group of data points that meets the standard is obtained, and the color of each data point in the group of data points that meets the standard is drawn according to the data value of each data point in the group of data points that meets the standard, so as to generate a heat map of the area corresponding to the group of data points that meets the standard.

[0064] The user can set the standard value or threshold of the data point through the execution body of Example 1 (for example, through the page displayed by the execution body of Example 1), or the user can set the standard value or threshold of the data point through other terminals or devices other than the execution body of Example 1, and the execution body of Example 1 obtains the standard value or threshold of the data point from the other terminals or devices.

[0065] Through the above-mentioned step-by-step diffusion process, the number of data points included in the n+1th group of data points is greater than the number of data points included in the nth group of data points, thereby achieving the growth of data points. If the number of data points included in a group of data points is greater than or equal to the standard value or threshold of the data points, it can be determined that the group of data points meets the standard, and the group of data points is the standard group of data points.

[0066] Since the map target point is a point on the map, and the center point of each group of data points is the map target point, each data point in each group of data points corresponds to a point on the map, and thus each group of data points corresponds to a certain area on the map, which is called the area corresponding to each group of data points. For any group of data points, the area corresponding to the group of data points is the area on the map covered by the square formed by the outermost data lines of the group of data points. That is, the area corresponding to the nth group of data points is the area of ​​the 3-square grid of the nth group of data points. n-1 ×3 n-1 The square formed by the outermost data point connection lines of the first row of data array (i.e., the data point connection lines of the third row)n-1 Row data point connection, 1st column data point connection, 3rd n-1 The square formed by the lines connecting the columns of data points) covers the area on the map.

[0067] Since the first group of data points has only one data point, the user can set the area on the map corresponding to the first group of data points through the execution subject of the first embodiment; or the user can set the area on the map corresponding to the first group of data points through other terminals or devices other than the execution subject of the first embodiment, and the execution subject of the first embodiment obtains the area on the map corresponding to the first group of data points from the other terminals or devices. The area on the map corresponding to the first group of data points can be a square area or a circular area on the map centered on the first group of data points.

[0068] After determining the data points of the target group, the execution body of the first embodiment can generate and display the heat map of the area corresponding to the data points of the target group. Among them, the execution body of the first embodiment can generate the heat map of the area corresponding to the data points of the target group according to the method of 1.1 or 1.2:

[0069] 1.1. When the number of data points contained in a group of data points meets the standard, the execution entity of Example 1 can draw the color of each data point in the group of data points that meets the standard according to the distance between each data point in the group of data points that meets the standard and the target point of the map, so as to generate a heat map of the area corresponding to the group of data points that meets the standard.

[0070] Wherein, drawing the color of the data point according to the distance between any data point in the target group data point and the map target point may include: determining the color corresponding to the data point according to the distance between any data point in the target group data point and the map target point (for example, the farther the data point is from the map target point, the lighter or darker its corresponding color); drawing a certain area on the map centered on the data point into the color corresponding to the data point. Specifically, the certain area centered on the data point can be called the corresponding area of ​​the data point, and the corresponding area of ​​the data point is generally a square area or a circular area. If the corresponding area of ​​the data point is a square area, the side length of the corresponding area of ​​the data point can be the distance between adjacent data points in the same row or column of the target group data point; if the corresponding area of ​​the data point is a circular area, the radius of the corresponding area of ​​the data point can be half of the distance between adjacent data points in the same row or column of the target group data point.

[0071] 1.2. When the number of data points contained in a group of data points meets the standard, the execution entity of Example 1 can obtain the data value of each data point in the group of data points that meets the standard, and draw the color of each data point in the group of data points that meets the standard according to the data value of each data point in the group of data points that meets the standard, so as to generate a heat map of the area corresponding to the group of data points that meets the standard.

[0072] The data value of each data point in the target group data point may be set or accessed by the user, for example, the data point may be offline data or static data, the data value may be an offline data value or a static data value, or the data value may be accessed through WebAPI. Drawing the color of each data point in the target group data point according to the data value of each data point in the target group data point may include: determining the color corresponding to any data point in the target group data point according to the data value of the data point (for example, the data point with a higher data value has a lighter or darker corresponding color); drawing a certain area on the map centered on the data point (same as 1.1) into the color corresponding to the data point.

[0073] In the first embodiment, after the target group data points are determined, the execution subject of the first embodiment can stop data diffusion until the user resets the data point standard value or threshold, or the user re-triggers the data diffusion process. Each time a map target point is determined, it can be regarded as triggering a data diffusion process.

[0074] In the first embodiment, data growth is achieved step by step by means of data diffusion, which can reduce the machine resources or memory required for data growth, increase the data growth rate, and thus improve the efficiency of drawing the heat map.

[0075] In the first embodiment, without the need for the user to access real data, the color of each data point in the target group data point can be drawn according to the distance between each data point in the target group data point and the map target point, and a heat map of the area corresponding to the target group data point can be generated. In this way, the heat map generation speed is faster and the heat map generation efficiency is higher. The generated heat map can be used as a data display simulation or as a data display template.

[0076] In the first embodiment, on the basis of increasing the data growth rate, the data value of each data point in the standard group data point can be obtained, and the color of each data point in the standard group data point can be drawn according to the data value of each data point in the standard group data point to generate a heat map of the area corresponding to the standard group data point. Since the data value can be freely changed by the user, it is also convenient to change the generated heat map, thereby improving the efficiency and flexibility of heat map generation.

[0077] In the first embodiment, the user can freely set the standard value or threshold of the data point, and can also freely set the shape or type of the heat map, so as to improve the efficiency or flexibility of heat map generation.

[0078] In the first embodiment, a heat map is used as a data display method, and the data points can represent various data such as industrial data, traffic data, and population data, thereby improving the efficiency and flexibility of heat map generation, thereby improving the efficiency and flexibility of data display.

[0080] A positioning module 202 is used to obtain a screen target point on the display screen and determine a map target point in the map corresponding to the screen target point; wherein the map target point is a first group of data points;

[0082] The drawing module 206 is used to draw the color of each data point in the data point group that meets the standard according to the distance between each data point in the data point group that meets the standard and the target point of the map when the number of data points included in a certain group of data points meets the standard, so as to generate a heat map of the area corresponding to the data point group that meets the standard; or, when the number of data points included in a certain group of data points meets the standard, obtain the data value of each data point in the data point group that meets the standard, and draw the color of each data point in the data point group that meets the standard according to the data value of each data point in the data point group that meets the standard, so as to generate a heat map of the area corresponding to the data point group that meets the standard.

[0083] Optionally, construct 3 with the nth group of data points as the center n ×3 n Level data array, including:

[0104] In the 1990s, improvements to a technology could be clearly distinguished as hardware improvements (for example, improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the method flow). However, with the development of technology, many improvements to the method flow today can be regarded as direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to ask a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0105] The controller can be implemented in any appropriate manner, for example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the (micro)processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in a purely computer-readable program code manner, the controller can be implemented in the form of a logic gate, a switch, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, this controller can be considered as a hardware component, and the devices included therein for implementing various functions can also be regarded as structures within the hardware component. Or even, the devices for implementing various functions can be regarded as both software modules for implementing the method and structures within the hardware component.
