Python繪圖之——matplotlib顏色與線條

  1. 常用顏色: 八種內建預設顏色縮寫
    b: blue
  g: green
  r: red
  c: cyan
  m: magenta
  y: yellow
  k: black
  w: white

其他顏色表示方法:灰色陰影,html 十六進位制RGB 元組

  1. 簡單例子:繪製y=x2曲線
import matplotlib.pyplot as plt   
plt.subplots(1, 1)
x= range(100)
y= [i**2 for i in x]
plt.plot(x, y, linewidth = '1', label = "test", color='y'
, linestyle=':', marker='|') plt.legend(loc='upper left') plt.show()

結果: 3. 第二個參考網址給出的linestyle可選引數:

'-'       solid line style
'--'      dashed line style
'-.'      dash-dot line style
':'       dotted line style

4.第二個參考網址給出的marker可選引數:

'.'       point marker
','       pixel marker
'o'       circle
marker 'v' triangle_down marker '^' triangle_up marker '<' triangle_left marker '>' triangle_right marker '1' tri_down marker '2' tri_up marker '3' tri_left marker '4' tri_right marker 's' square marker 'p' pentagon marker '*' star marker
'h' hexagon1 marker 'H' hexagon2 marker '+' plus marker 'x' x marker 'D' diamond marker 'd' thin_diamond marker '|' vline marker '_' hline marker
