代码：

plt.subplots(1, 1)x= range(100)y= [i**2 for i in x]plt.plot(x, y, linewidth = '1', label = "test", color=' coral ', linestyle=':', marker='|')plt.legend(loc='upper left')plt.show()

结果：

说明：其实上面color=’ coral ‘中，可以换成color=’ #054E9F’，每两个十六进制数分别代表R、G、B分量：

 

第二个参考网址给出了linestyle可选参数：

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

第二个参考网址给出了marker可选参数：

'.'       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

上面对应的颜色：

另外的显示方式：

装了seaborn扩展的话，在字典seaborn.xkcd_rgb中包含所有的xkcd crowdsourced color names。如下：

plt.plot([1,2], lw=4, c=seaborn.xkcd_rgb['baby poop green'])

所有颜色如下：
