python数据分析plt颜色样式设置

根据颜色代码:

https://m.wang1314.com/doc/webapp/topic/21084865.html

绘制多条线 y=sin(x)+1  y=sin(x)+2  y=sin(x)+3 ……y=sin(x)+7  ,每个颜色不同,点样式不同,线类型循环重复。

 

‘.’:点(point marker)               ‘,’:像素点(pixel marker)

    ‘o’:圆形(circle marker)            ‘v’:朝下三角形(triangle_down marker)

    ‘^’:朝上三角形(triangle_up marker)       ‘<‘:朝左三角形(triangle_left marker)

    ‘>’:朝右三角形(triangle_right marker)    ‘1’:(tri_down marker)

    ‘2’:(tri_up marker)              ‘3’:(tri_left marker)

    ‘4’:(tri_right marker)            ‘s’:正方形(square marker)

    ‘p’:五边星(pentagon marker)          ‘*’:星型(star marker)

    ‘h’:1号六角形(hexagon1 marker)        ‘H’:2号六角形(hexagon2 marker)

    ‘+’:+号标记(plus marker)            ‘x’:x号标记(x marker)

    ‘D’:菱形(diamond marker)           ‘d’:小型菱形(thin_diamond marker)

    ‘|’:垂直线形(vline marker)           ‘_’:水平线形(hline marker)

 

 

我的答案:

import matplotlib.pyplot as plt

import numpy as np

colorlist=plt.cm.cool(np.linspace(0,1,7))

markers=["D","x","h",".","^",">","v"]

x=np.linspace(0,4*np.pi)

y=np.sin(x)+1

for i in range(0,7):

    plt.plot(x,y+i,color=colorlist[i],linestyle=":",marker=markers[i])

plt.show()
