matplotlib指定线条的颜色以及标记
matplotlib指定线条的颜色以及标记
一、总结
一句话总结:
color颜色
marker标记,markersize为标记大小
linestyle线样式,linewidth线宽
plt.plot(x,y,color='red', marker='o', linestyle='dashed',linewidth=2, markersize=12)
二、matplotlib指定线条的颜色以及标记
import numpy as np import matplotlib.pyplot as plt # 设置matplotlib库字体的非衬线字体为黑体 plt.rcParams["font.sans-serif"]=["SimHei"] # 设置matplotlib库字体族为非衬线字体 plt.rcParams["font.family"]="sans-serif" fig, ax = plt.subplots() # 取消边框 for key, spine in ax.spines.items(): # 'left', 'right', 'bottom', 'top' if key == 'left' or key == 'right': spine.set_visible(False) plt.xticks([]) plt.yticks([]) x=[1,2,3,4,5] y=[4,9,6,8,3] y_mean=np.mean(y).repeat(5) print(y_mean) #plt.plot(x,y,'ro') plt.plot(x,y,color='red', marker='o', linestyle='dashed',linewidth=2, markersize=12) plt.plot(x,y_mean,'k--') plt.text(0.2,6,r'x均值', fontdict={'size':16,'color':'r'}) plt.text(0.6,6,r'$:\mu_x$', fontdict={'size':16,'color':'r'}) plt.show()
