 # note: problem with <type 'array'> in pcolor

[The following problem seems to occur with Numeric but not with numarray]

The following code

···

======================
from matplotlib.matlab import *

# x = arange(0,20,.2) y = arange(0,20,.2) X, Y = meshgrid(x,y) z=zeros((len(x),len(y)),'f') for i in enumerate(x):     for j in enumerate(y):         z[i][j]=10*sin(i*j)#or z[i,j]=10*sin(i*j) pcolor(X,Y, transpose(z),shading='faceted') show()

breaks in the module color.py

# =============================    def get_color(self, val, valmin, valmax):        # map val to a range from 0 to 1        if iterable(val):           s = "val must be a scalar. Perhaps you meant to call get_colors?"#print val,type(val)           raise ValueError, s#print valmin, valmax#print val,type(val)        ind = self.indmax*(val-valmin)/(valmax-valmin)        return self.rgbs[self._bound_ind(ind)]

because the test for iterable fails since the element C[i,j] is type
<array>. One solution is to change the code section around line 1126 in
axes.py from c = C[i,j] to the following.

=====================
for i in range(Nx-1):
for j in range(Ny-1):

# c = C[i][j]

the form C[i][j] seems to always return float.
