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()
