[Matplotlib-users] plot with marker color coded according to z-value

[elmar w. <el...@ne...>]

Hi,

is there a way to adjust the marker color in a xy-plot in relation to 
the value of a third parameter. Something as the following - not working 
- example 1.

Example 2 is working but rather slow for large arrays.

cheers
Elmar




# example 1

import matplotlib.pyplot as plt

x = [1,2,3,4]
y = x
c = ((1.0, 0.0, 0.0), (0.8, 0.1, 0.1), (0.6, 0.2, 0.6), (0.4, 0.3, 0.3))

plt.plot(x,y, color=c, marker='s')
plt.show()


example 2:

import matplotlib.pyplot as plt

x = [1,2,3,4]
y = x
c = ((1.0, 0.0, 0.0), (0.8, 0.1, 0.1), (0.6, 0.2, 0.6), (0.4, 0.3, 0.3))

for i in range(len(x)):
     plt.plot(x[i], y[i], color=c[i], marker='s')

plt.show()
