Python matplotlib绘制饼状图功能示例
人气:0本文实例讲述了Python matplotlib绘制饼状图功能。分享给大家供大家参考,具体如下:
一 代码
import numpy as np import matplotlib.pyplot as plt #The slices will be ordered and plotted counter-clockwise. labels ='Frogs','Hogs','Dogs','Logs' sizes =[15,30,45,10] colors =['yellowgreen','gold','#FF0000','lightcoral'] #使饼状图中第2片和第4片裂开 explode =(0,0.1,0,0.1) fig = plt.figure() ax = fig.gca() ax.pie(np.random.random(4), explode=explode, labels=labels, colors=colors, autopct='%1.1f%%', shadow=True, startangle=90, radius=0.25, center=(0,0), frame=True) ax.pie(np.random.random(4), explode=explode, labels=labels, colors=colors, autopct='%1.1f%%', shadow=True, startangle=90, radius=0.25, center=(1,1), frame=True) ax.pie(np.random.random(4), explode=explode, labels=labels, colors=colors, autopct='%1.1f%%', shadow=True, startangle=90, radius=0.25, center=(0,1), frame=True) ax.pie(np.random.random(4), explode=explode, labels=labels, colors=colors, autopct='%1.1f%%', shadow=True, startangle=90, radius=0.25, center=(1,0), frame=True) #设置坐标轴刻度 ax.set_xticks([0,1]) ax.set_yticks([0,1]) #设置坐标轴刻度上显示的标签 ax.set_xticklabels(["Sunny","Cloudy"]) ax.set_yticklabels(["Dry","Rainy"]) #设置坐标轴跨度 ax.set_xlim((-0.5,1.5)) ax.set_ylim((-0.5,1.5)) #设置纵横比相等 ax.set_aspect('equal') plt.show()
二 运行结果
希望本文所述对大家Python程序设计有所帮助。
