Hi John
Here's a test script that gives the wrongly exported SVG image. I'm
viewing with EOG. When I edit to add "style="opacity:0.15"" it works
fine, so there's no prob with EOG.
from pylab import *
import matplotlib.numerix.ma as ma
from matplotlib.colors import ListedColormap
A = flipud(array([[1,2,3,4,5],[1,3,4,5,6],[1,1,4,5,7]]))
M = where(A==1,1,0)
B = ma.array(A,mask=M)
C = ListedColormap(['r','#FF00FF','y','g','b','#FFFF00'])
x = [0,5,10,15,20]
y = [0,5,10]
X,Y = meshgrid(x,y)
X = ma.array(X,mask=B.mask())
Y = ma.array(Y,mask=B.mask())
figure()
pcolor(X,Y,B,alpha=0.15,shading='flat',cmap=C)
hold(True)
contour(x,y,B)
xlabel('something')
ylabel('else')
Cheers
JP
