本文实例为大家分享了python画折线图的具体代码,供大家参考,具体内容如下
# encoding=utf-8 import matplotlib.pyplot as plt from pylab import * #支持中文 mpl.rcParams['font.sans-serif'] = ['SimHei'] names = ['5', '10', '15', '20', '25'] x = range(len(names)) y = [0.855, 0.84, 0.835, 0.815, 0.81] y1=[0.86,0.85,0.853,0.849,0.83] #plt.plot(x, y, 'ro-') #plt.plot(x, y1, 'bo-') #pl.xlim(-1, 11) # 限定横轴的范围 #pl.ylim(-1, 110) # 限定纵轴的范围 plt.plot(x, y, marker='o', mec='r', mfc='w',label=u'y=x^2曲线图') plt.plot(x, y1, marker='*', ms=10,label=u'y=x^3曲线图') plt.legend() # 让图例生效 plt.xticks(x, names, rotation=45) plt.margins(0) plt.subplots_adjust(bottom=0.15) plt.xlabel(u"time(s)邻居") #X轴标签 plt.ylabel("RMSE") #Y轴标签 plt.title("A simple plot") #标题 plt.show()
