Xiaobian shares with you how to draw radar maps in big data development. I believe most people still don't know much about them. Therefore, I share this article for your reference. I hope you will gain a lot after reading this article. Let's find out together.

Radar charts, also known as spider webs, debra charts, polar charts, web charts, star charts, star charts, etc., are common financial analysis reports. Spiderweb charts can represent data for multiple variables as a two-dimensional graph, and all three variables on the axis start from the same starting point. Spiderweb or radar charts are often used to see how different factors are related to the same thing. This article will guide you how to use Edraw software to quickly draw radar map, spider web map.

Create Radar Charts

Open Edraw Diagram software, select "New"--"Chart"--"Spider (Radar) Diagram"--"Create" to open the canvas.

The left side of the operation interface is the symbol library, from which users can select appropriate radar diagram templates and add them to the canvas. According to different display scenes, radar map can be divided into ordinary radar map, area radar map, percentage radar map and polarity map. This paper introduces basic operation skills by taking common radar chart as an example.

Loading data from files

Edraw graphical software supports users to import data locally and generate radar maps with one click. The specific operation method is as follows:

1. Start the text template: Create another blank canvas and drag "How to use" in the symbol library to the canvas.

Choose to copy the text content in "example 1" or "example 2."

2. Edit data: Create a new txt notepad locally on the computer, paste the text content copied above into the txt notepad. According to the template, make custom modifications. The first line is the name of the category, from left to right, in turn. The second row to the nth row are the family, the first column is the family name, and the other columns are data. Commas are required to separate each piece of data to avoid import errors.

3. Import data: In the chart editing canvas, the mouse is close to the chart, and the floating button appears. Click the first item "Load data from file" and select the text just edited to import with one click.

4. Change the data: After the data is loaded, a radar map is generated with one key. If you find that the data is incorrect, you can double-click the data text to modify it. The data structure of the radar map changes with each modification.

5. Adjust the radar chart size: Move the mouse to the vertex, drag the yellow control point, and adjust the radar chart size.

Advanced Settings for Radar Charts

Floating buttons for radar charts, complete with radar chart settings. Users can customize settings here according to their needs.

1, set the number of series: enter the value, determine the number of series, the number of series in this example is the number of students.

2. Set the number of axes: enter a numerical value to determine the number of axes. In this example, the number of axes is the number of accounts.

3. Set the number of circles: that is, the number of gray hexagons, the initial value is 8. In this example, it is assumed that the full score of the subject is 100 points, so the number of circles can be set to 10.

4, set the maximum value: that is, the maximum value of the axial direction, the maximum value in this example can be set to 100.

5. Hide data label: After clicking, all data content on radar image will be blocked.

6. Display legend on the right/bottom: You can customize the display position of legend.

7. Appearance options: The options set are rich, and you can modify data precision, data format, prefix unit, suffix unit and mark style.
