本文介绍了如何在Python中使用matplotlib库读取Excel数据并绘制雷达图。详细步骤包括数据预处理、设置雷达图参数以及绘制图形的过程。

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import cairosvg

from openpyxl import load_workbook
import  time
def plot_radar(data,lables,id):
    '''
    the first column of the data is the cluster name;
    the second column is the number of each cluster;
    the last are those to describe the center of each cluster.
    '''


    # labels = data.iloc[:, 2:].columns
    # centers = pd.concat([data.iloc[:, 2:], data.iloc[:, 2]], axis=1)
    lables=["","","","","","","","",""]
    for ele in range(len(id)):
        plt.rcParams["font.sans-serif"] = ["KaiTi"]
        # plt.rcParams['font.family'] = 'YaHei Consolas Hybrid'  # 设置字体样式
        plt.rcParams['font.size'] = '15'  # 设置字体大小
        plt.rcParams["axes.unicode_minus"] = False

        centers=[data[ele]]
        for i in range(len(centers[0])):
            # centers[0][i
            centers[0][i]/=10
        centers[0].append(centers[0][0])

        centers = np.array(centers)

        n = 8
