慧学（28）：Origin雷达图绘图学习

摘要：雷达图，又称蜘蛛图或极坐标图，是一种利用极坐标系绘制的统计图表，用来展示多个变量在同一维度下的比较。图中各个指标维度均匀排列在圆周上，变量数值则以半径长度表示，不同对象的数据通过折线或填充区域相连，从而形成多边形。

一、思维导图（Mind mapping）

二、雷达图简介（Introduction to radar charts）

雷达图，又称蜘蛛图或极坐标图，是一种利用极坐标系绘制的统计图表，用来展示多个变量在同一维度下的比较。图中各个指标维度均匀排列在圆周上，变量数值则以半径长度表示，不同对象的数据通过折线或填充区域相连，从而形成多边形。

A radar chart, also known as a spider chart or polar coordinate chart, is a statistical chart created using polar coordinates to compare multiple variables along the same dimension. Each indicator dimension is evenly arranged on the circumference of a circle, with the variable values represented by the radius. Data from different objects are connected by broken lines or filled areas, forming polygons.

雷达图的主要用途包括以下几个方面。首先，它能够直观地展示多个样本在不同指标上的相对优势与不足，实现多指标对比。其次，通过图形的面积或形状差异，可以快速判断各对象的整体表现，便于进行综合评价。再次，雷达图适用于揭示样本之间的相似性或差异性，常用于企业竞争力分析、绩效评估以及问卷调查结果展示等。由于能够在二维平面中呈现多维数据，雷达图在数据可视化、市场分析、绩效考核、产品对比等领域被广泛应用。

Radar charts have several key uses. First, they can intuitively display the relative strengths and weaknesses of multiple samples across various metrics, enabling multi-metric comparison. Second, by analyzing differences in area or shape, the overall performance of each object can be quickly determined, facilitating comprehensive evaluation. Third, radar charts are suitable for revealing similarities or differences between samples and are commonly used in corporate competitiveness analysis, performance evaluation, and survey results presentation. Because they can present multidimensional data in a two-dimensional plane, radar charts are widely used in data visualization, market analysis, performance evaluation, product comparison, and other fields.

三、绘制雷达图的步骤（Steps to draw a radar chart）

1、准备数据（Prepare the data）

在打开Origin后，先新建一个工作表。将各项指标或维度名称输入到第一列，例如“指标1”至“指标5”。然后，在后续的列中依次录入不同对象的数据，如“A公司”、“B公司”和“C公司”。

After opening Origin, create a new worksheet. Enter the names of each indicator or dimension in the first column, for example, "Indicator 1" through "Indicator 5." Then, enter the data for different objects in subsequent columns, such as "Company A," "Company B," and "Company C."

2、插入雷达图（Insert a radar chart）

用鼠标选中包含标签行的完整数据区域，在菜单栏中点击绘图工具，再依次选择“专业图”中的“雷达图”。此时，Origin 会自动生成一个基础的雷达图，并将各列数据绘制在图形上。

Use your mouse to select the entire data area, including the label row. Click Drawing Tools in the menu bar, then select "Radar Chart" from "Professional Charts." Origin will automatically generate a basic radar chart and plot each column of data on the graph.

3、修改图表样式（Modify chart style）

在生成雷达图后，可以进一步美化图形。如果想要修改图形元素，双击图中的曲线，在弹出的绘图属性对话框中首先将绘图属性改为独立，之后就可以对每条线设置不同颜色和线型，并调整标记的形状、大小及颜色。

After generating a radar chart, you can further enhance it. To modify the graphic elements, double-click the curve in the chart. In the displayed Plot Properties dialog box, first change the Plot Properties to Independent. You can then set a different color and line type for each line and adjust the shape, size, and color of the markers.

4、添加文字标识（Add a text logo）

在图表样式美化完成后，还可以进一步完善。右击选择添加或修改图层标题，即可图表上方添加标题，例如输入“公司对比雷达图”。如果需要更改，可右键打开编辑对话框进行调整。

After you've finished creating a beautiful chart, you can further refine it. Right-click and select Add or Modify Layer Title to add a title above the chart. For example, enter "Company Comparison Radar Chart." If you need to change it, right-click to open the Edit dialog box and make adjustments.

可以通过添加文本，来为每条线添加标识。

You can add text to label each line.

5、保存图表（Save the chart）

最终，可以在“文件”菜单中选择“导出图”，将生成的图表保存为 PNG、TIFF或 EPS 等格式，以便后续插入论文或研究报告中使用。

Finally, you can select "Export Figure" in the "File" menu to save the generated chart in formats such as PNG, TIFF, or EPS for subsequent use in papers or research reports.
