1、柱状图
import matplotlib.pyplot as plt plt.rcParams['font.sans-serif']=['SimHei']#支持中文标题 classes=['class1','class2','class3'] scores=[70,80,60] name=['A班','B班','C版'] plt.bar(classes,scores) plt.title('三班成绩柱状图') plt.xlabel('班级') plt.ylabel('成绩') plt.xticks(classes,name) plt.text('class1',71,70) plt.text('class2',81,80) plt.text('class3',61,60) plt.show()
2、直方图
import matplotlib as mpl import matplotlib.pyplot as plt height=[168,155,182,170,173,161,155,173,176,181,166,172,170] bins=range(150,191,5)#从150到191,步长为5 plt.hist(height,bins=bins) plt.show()
3、阶梯图
import matplotlib.pyplot as plt plt.rcParams['font.sans-serif']=['SimHei'] year=range(2005,2020) height=[168,155,182,170,173,161,155,173,176,181,166,172,170,180,187] plt.step(year,height) plt.show()
4、折线图
import matplotlib.pyplot as plt year=range(2005,2020) height=[168,155,182,170,173,161,155,173,176,181,166,172,170,180,187] plt.plot(year,height) plt.show()
5、饼图
import matplotlib.pyplot as plt plt.rcParams['font.sans-serif']=['SimHei']#支持中文标题 labels=['房贷','饮食','出行','教育'] data=[8000,2000,2000,3000] plt.pie(data,labels=labels,autopct='%1.1f%%') plt.show()
