折线图： import matplotlib.pyplot as plt y1=[10,13,5,40,30,60,70,12,55,25] x1=range(0,10) x2=range(0,10) y2=[5,8,0,30,20,40,50,10,40,15] plt.plot(x1,y1,label='Frist line',linewidth=3,color='r',marker='o', markerfacecolor='blue',markersize=12) plt.plot(x2,y2,label='second line') plt.xlabel('Plot Number') plt.ylabel('Important var') plt.title('Interesting Graph/nCheck it out') plt.legend() plt.show() 这里写图片描述

条形图

import matplotlib.pyplot as plty1=[10,13,5,40,30,60,70,12,55,25]x1=range(0,20,2)x2=range(1,21,2)y2=[5,8,0,30,20,40,50,10,40,15]plt.bar(x1,y1,label='Frist line')#plt.bar(x2,y2,label='second line',color='r')plt.xlabel('Plot Number')plt.ylabel('Important var')plt.title('Interesting Graph/nCheck it out')plt.legend()plt.show()

直方图：

import matplotlib.pyplot as pltpopulation_ages = [22,55,62,45,21,22,34,42,42,4,99,102, 110,120,121,122,130,111,115,112,80,75, 65,54,44,43,42,48]x=range(0,130,10)plt.hist(population_ages,x,rwidth=0.8,color='r',histtype='stepfilled')plt.xlabel('Plot Number')plt.ylabel('Important var')plt.title('Interesting Graph/nCheck it out')plt.legend()plt.show()

散点图：

import matplotlib.pyplot as pltpopulation_ages = [22,55,62,45,21,22,34,42,42,4,99,102, 110,120,121,122,130,111,115,112,80,75, 65,54,44,43,42,48]x=range(0,len(population_ages))plt.scatter(x,population_ages,label='frist label',s=20)help(plt.scatter)plt.xlabel('x')plt.ylabel('y')plt.title('Interesting Graph/nCheck it out')plt.legend()plt.show()
