对于变量z的许多不同值,我有两个变量(x,y)的一系列线图.我通常会添加带有这样的图例的线条图:

import matplotlib.pyplot as plt

fig = plt.figure()
ax  = fig.add_subplot(111)
# suppose mydata is a list of tuples containing (xs, ys, z) 
# where xs and ys are lists of x's and y's and z is a number. 
legns = []
for(xs,ys,z) in mydata:
   pl = ax.plot(xs,ys,color = (z,0,0))
   legns.append("z = %f"%(z))
ax.legends(legns) 
plt.show()

但是我有太多的图表,传说将涵盖图表.我宁愿用一个颜色条来表示与颜色对应的z的值.我无法在galery中找到类似的东西,我所有的尝试都处理了colorbar失败.显然我必须在尝试添加颜色条之前创建一组绘图.

是否有捷径可寻？谢谢.

编辑(澄清):

我想做这样的事情:

import matplotlib.pyplot as plt
import matplotlib.cm     as cm

fig = plt.figure()
ax  = fig.add_subplot(111)
mycmap = cm.hot
# suppose mydata is …
