plt.plot(x, y_train, marker='o', mec='r', mfc='w',label='uniprot90_train')
plt.plot(x, y_test, marker='*', ms=10,label='uniprot90_test')
plt.legend() # 让图例生效
plt.xticks(x, names, rotation=1)
plt.margins(0)
plt.subplots_adjust(bottom=0.10)
plt.xlabel('the length') #X轴标签
plt.ylabel("f1") #Y轴标签
pyplot.yticks([0.750,0.800,0.850])
#plt.title("A simple plot") #标题
plt.savefig('D:\\f1.jpg',dpi = 900)
结果如下：
