二、雷达图简介 (Introduction to radar charts)

雷达图，也称为蜘蛛网图、极坐标图或星形图，是一种将多个维度的数据可视化的二维图表。它由一个从中心点发射出多个轴的圆形网格组成，每个轴代表一个变量或维度。将单个数据序列在各个轴上的值连接起来，就形成一个多边形，用于综合对比多个对象的整体属性或分析某个对象在不同维度上的强弱项。

A radar chart, also known as a spider web chart, polar coordinate chart, or star plot, is a two-dimensional graphical tool for visualizing multidimensional data. It consists of a circular grid with multiple axes radiating from a central point, where each axis represents a variable or dimension. By connecting the values of a single data series across these axes, a polygon is formed, enabling comprehensive comparison of the overall attributes of multiple objects or analysis of an individual object's strengths and weaknesses across different dimensions.

在Origin中创建雷达图有两种核心方法，分别是使用内置雷达图模板和极坐标图。第一种方式更适合新手和快速绘图。今天小编使用内置雷达图模板绘制雷达图。

There are two core methods for creating radar charts in Origin: using the built-in radar chart template and utilizing polar coordinate plots. The first approach is more suitable for beginners and rapid plotting. Today, I will demonstrate how to create a radar chart using the built-in radar chart template.

三、绘制步骤（Step-by-step guide to drawing a radar chart）

首先准备好数据，将数据导入到表格中，通常，每一列代表一个变量（维度），每一行代表一个观测对象（一组数据）。

First, prepare your data and import it into the worksheet. Typically, each column represents a variable (dimension), and each row represents an observation (a set of data).

然后用鼠标选中表格中所有数据，点击菜单栏中的“绘图”选项，在绘图类型选择专业图中的雷达图。确定好之后Origin就会自动生成一个雷达图，每个材料的数据会形成一条独立的、闭合的线。另外使用内置雷达图模板可以自动生成图例。

Then, use the mouse to select all the data in the worksheet. Click on the "Plot" option in the menu bar, and choose "Radar Chart" under the "Specialized Graphs" category in the plot type selection. After confirming, Origin will automatically generate a radar chart, where the data for each material will form a separate, closed line. Additionally, using the built-in radar chart template allows for automatic generation of the legend.

生成的雷达图可能比较基础，可以进一步调整图形样式。双击图中的线条，会弹出绘图属性表格，首先在“组”选项中选择“独立”，然后就可以点击不同线条，设置不同的颜色、线型、标记类型。

The generated radar chart may appear quite basic, but its graphical style can be further adjusted. By double-clicking on the lines in the chart, a plot properties dialog box will pop up. First, select "Independent" under the "Group" option. Then, you can click on different lines to set distinct colors, line styles, and marker types for each.

最后给图中每条线手动添加文字标识，让图形清晰可读。在自己希望标签出现的位置右击鼠标，就会弹出文本框，输入标识名称即可。

Finally, manually add text labels to each line in the chart to enhance clarity and readability. Right-click at the desired position where you want the label to appear, and a text box will pop up. Simply enter the identification name into the text box.
