For convenience of understanding, a specific flow of an embodiment of the present invention is described below, and referring to fig. 1, a first embodiment of a radar map generation method in an embodiment of the present invention includes:
101. acquiring an image creating instruction, wherein the image creating instruction comprises the number of parameters represented by the radar map;
it is to be understood that the executing subject of the present invention may be a radar map generating apparatus, and may also be a terminal or a server, which is not limited herein. The embodiment of the present invention is described by taking a server as an execution subject.
It is emphasized that the parameter values and parameter numbers may be stored in nodes of a blockchain in order to ensure privacy and security of the user.
In this embodiment, the user can view the radar chart he wants through the terminal device, analyze the financial radar chart in the fixed form, and draw the numbers or ratios obtained by various financial analyses of the company on a circular fixed form to express the financial status of the company, so that the user can clearly know the change situation and the quality trend of various financial indexes of the company, and the method has the characteristics of comprehensiveness, clearness, intuition, easy judgment and the like. Specifically, a user may view the radar map through a browser. In this embodiment, the image creating instruction may be generated according to data input by a user, or may be generated by inputting various ability values of a player through data searched by the user in a browser, for example, when a football coach analyzes the ability of the player, a radar map of the ability of the player is generated, or when the user starts the browser, the terminal device detects a keyword input by the user, searches for related data according to the keyword, and generates the image creating instruction according to the number of parameters and parameter values corresponding to the related data, thereby generating the radar map.
In this embodiment, the radar map mainly includes a basic frame map of the radar, a radar map area, and pattern information, where the basic frame map is a regular polygon image set according to the number of parameters, and a position of each vertex in the image represents a maximum value of the parameter, that is, when a vertex of the radar map is located at a vertex of the basic frame map, a parameter value of a parameter item represented by the vertex of the radar map reaches the maximum value, and in practical application, the number of vertices of the basic frame map is at least three, and a triangle is formed, so that the number of parameters is an integer not less than 3.
102. Drawing a corresponding basic frame graph by using canvas labels according to the number of parameters characterized by the radar graph, wherein the basic frame graph comprises the first vertexes with the number being the same as that of the parameters;
in practical applications, the number of parameters is an integer no less than 3, the canvas tag is canvas, which is a new tag appearing in HTML5(Hyper Text Markup Language), and like all dom objects, it has its own properties, methods and events, among which there are drawing methods. canvases have a variety of drawing paths, rectangles, circles, characters, and methods of adding images. The canvas element may use JavaScript to draw an image on a web page, the canvas is a canvas on which the image is drawn, and the canvas may be a rectangular area, each pixel of which may be controlled by a user. Therefore, based on the radar map drawn by canvas, the user can perform personalized operation, and the interactivity of the radar map is improved. When constructing a radar graph using canvas, a canvas element may first be added to the HTML5 page. The id, width and height of the canvas element may be specified when the canvas element is added, for example, the id, width and height of the canvas element may be specified using the following procedure:
<canvas id＝"myCanvas"width＝"200"height＝"100"></canvas>
in this embodiment, the basic frame diagram is drawn by a canvas, and the coordinates mentioned in this embodiment, that is, the canvas watch, are mainly obtained by obtaining coordinates of a plurality of vertices of the basic frame diagram in a canvas coordinate system and connecting the coordinates adjacently to obtain the basic frame diagram.
103. Acquiring a parameter value input by a user, and calculating a coordinate of a second vertex of the radar chart according to the parameter value and the coordinate of the first vertex in the coordinate system of the canvas label;
in this embodiment, the parameter value may be input by a user or obtained from a server, and specifically, the terminal device may obtain the parameter data from the server. Specifically, AJAX (Asynchronous JavaScript And XML) may be used to obtain the parameter data from the server. AJAX is a web page development technique for creating interactive web page applications. By exchanging a small amount of data with the server in the background, AJAX can enable the webpage to be updated asynchronously, so that the part of the webpage can be updated without reloading the whole webpage. The core of AJAX is JavaScript object XmlHttp Request. The object is introduced for the first time in Internet Explorer 5, which is a technology supporting asynchronous requests, and XmlHttp Request enables a user to make a Request to a server using JavaScript and process a response without blocking the user.
In this embodiment, the canvas coordinate of the second vertex is mainly the full value of the parameter represented by each vertex, for example, when the trainer analyzes each ability of the player, the full value of each ability is set to 100, and the parameter value of a certain ability of a certain player is 75, the canvas coordinate of the first vertex corresponding to the ability is scaled by 1:075, so as to obtain the second vertex of the ability, and the canvas coordinate of the second vertex of the radar map is obtained by scaling all the second vertices of the ability respectively.
In this embodiment, an initial point may be set in the basic frame map, and a corresponding relationship may be set for the first vertex of each basic frame map and the parameter of the radar map characterization according to the order of the parameter of the characterization, which is input by the user, counterclockwise or clockwise
In this embodiment, after the parameters corresponding to the radar map are obtained, the canvas coordinates corresponding to each data point included in the parameters may be calculated, and then the parameters are drawn as the radar map. For example, js (javascript) may be used to process data of each dimension of the radar map, and calculate canvas coordinates corresponding to each data point.
In this embodiment, the input of the user includes parameters to be characterized by the radar map and the number of the parameters, and when the basic frame map is drawn, according to the position of the vertex of the basic frame map in the coordinate system, the corresponding relationship between the parameters and the vertex may be set, for example, the vertex set on the x-axis of the coordinate system is an initial vertex, the vertex corresponds to the first parameter input by the user, and the parameters input by the user are respectively made to correspond to the vertices in the order from the initial vertex in the clockwise direction or the counterclockwise direction, so that the first vertex and the parameters have the corresponding relationship.
104. Setting corresponding file information according to the coordinates of the second vertex;
in this embodiment, the second coordinate value may be set with a preset document near the coordinate value, where the document is mainly set according to different application scenarios, for example, when a coach analyzes various abilities of a player, fields of the abilities are set near vertices of a basic frame diagram, such as pass, endurance, speed, strength, defense, and shooting.
In this embodiment, after the background frame of the regular polygon is constructed, when the user inputs the parameter value, the coordinate value of the second vertex is changed according to the parameter value, and the set document information is also dynamically changed according to the coordinate value of the second vertex.
105. Generating a radar map area according to the coordinates of the second vertex, and combining the radar map area, the file information and the basic frame map to obtain and display a finished radar map;
in this embodiment, the second vertices are mainly connected to the coordinate original, and the distance between the two points is calculated according to the coordinates to obtain the radius of the radar map, since the basic frame map is a regular polygon and the input parameter items are multiple items, the radar map also includes multiple second vertices, the radii of multiple radar maps can be obtained according to the connection between different second vertices and the coordinate original, the inner area of the basic frame map is cut according to the radii of adjacent radar maps, and the actual radar map area can be cut by using a canvas.
In this embodiment, after trimming the radar map area, the radar map area needs to be depicted, the radar map area is displayed, and the radar map is generated, which is mainly completed by three different canvases, wherein a first canvas is used as a canvas for finally presenting an effect, and includes the radar map area, a small circle at a second vertex, a stroke connecting the vertices, and the like; a second canvas is used to depict the static radar map area of the full version; and a third canvas draws a covering layer for covering the static radar map area of the full version, generates a dynamic effect of delineation, and combines the delineated radar map, the file information and the basic frame map to obtain a finished radar map.

In addition, the invention also relates to a block chain technology, and parameter values and parameter numbers can be stored in the block chain.

in this embodiment, before calculating the coordinates of each vertex, one vertex of the regular polygon is set on the x-axis of the canvas coordinate axis, and an circumscribed circle is drawn outside the regular polygon, as shown in fig. 9, where α is an included angle between a connection line of the vertex and the origin of coordinates and the x-axis, the included angle is calculated to be half of an internal angle of the regular polygon, and the internal angle is also different according to regular polygons with different numbers of edges, the internal angle of the regular polygon is pi × 2/m, where m is the number of edges of the regular polygon, that is, the number of vertices of the regular polygon, and the calculation formula of each vertex is calculated by the following formula:
(r*cos(α*(m-1))，r*sin(α*(m-1)))
and r is the radius of the circumscribed circle, and after the coordinates of the vertexes are obtained, the basic frame graph can be drawn according to the vertex coordinates.
