matplotlib实例笔记
下面的图型是在一幅画布上建立的四个球员相关数据的极坐标图
关于这个图的代码如下：
1 #_*_coding:utf-8_*_ 2 import numpy as np 3 import matplotlib.pyplot as plt 4 from matplotlib.font_manager import FontProperties 5 plt.style.use('ggplot') 6 7 font=FontProperties(fname=r'c:\windows\fonts\simsun.ttc',size=12) 8 # 本行是为了有效显示中文的字体与大小 9 10 ability_size=6 11 ability_label=['进攻','防守','盘带','速度','体力','射术'] 12 13 # 创建每个极坐标的位置 14 ax1=plt.subplot(221,projection='polar') 15 ax2=plt.subplot(222,projection='polar') 16 ax3=plt.subplot(223,projection='polar') 17 ax4=plt.subplot(224,projection='polar') 18 19 player={ 20 'M': np.random.randint(size=ability_size, low=60, high=99), 21 'H': np.random.randint(size=ability_size, low=60, high=99), 22 'P': np.random.randint(size=ability_size, low=60, high=99), 23 'Q': np.random.randint(size=ability_size, low=60, high=99), 24 } 25 26 theta=np.linspace(0,2*np.pi,6,endpoint=False) 27 theta=np.append(theta,theta[0]) 28 29 #下面分别画四个球员的能力极坐标图 30 player['M']=np.append(player['M'],player['M'][0]) 31 ax1.plot(theta,player['M'],'r') 32 ax1.fill(theta,player['M'],'r',alpha=0.3) 33 ax1.set_xticks(theta) 34 ax1.set_xticklabels(ability_label,fontproperties=font) 35 ax1.set_title('梅西',fontproperties=font,color='r',size=20) 36 ax1.set_yticks([20,40,60,80,100]) 37 38 player['H']=np.append(player['H'],player['H'][0]) 39 ax2.plot(theta,player['H'],'g') 40 ax2.fill(theta,player['H'],'g',alpha=0.3) 41 ax2.set_xticks(theta) 42 ax2.set_xticklabels(ability_label,fontproperties=font) 43 ax2.set_title('哈维',fontproperties=font,color='g',size=20) 44 ax2.set_yticks([20,40,60,80,100]) 45 46 player['P']=np.append(player['P'],player['P'][0]) 47 ax3.plot(theta,player['P'],'b') 48 ax3.fill(theta,player['P'],'b',alpha=0.3) 49 ax3.set_xticks(theta) 50 ax3.set_xticklabels(ability_label,fontproperties=font) 51 ax3.set_title('皮克',fontproperties=font,color='b',size=20) 52 ax3.set_yticks([20,40,60,80,100]) 53 54 player['Q']=np.append(player['Q'],player['Q'][0]) 55 ax4.plot(theta,player['Q'],'y') 56 ax4.fill(theta,player['Q'],'y',alpha=0.3) 57 ax4.set_xticks(theta) 58 ax4.set_xticklabels(ability_label,fontproperties=font) 59 ax4.set_title('切赫',fontproperties=font,color='y',size=20) 60 ax4.set_yticks([20,40,60,80,100]) 61 62 plt.show()
上述代码也可以利用for循环简化一下
