[Matplotlib-users] logairthmic contour plot

[jonasr <jon...@we...>]

Hi, 

im actually trying to make a countour plot Z=f(X,Y) from two variables X,Y .
My Problem is that i have to use a logarithmic scale for the Z values.
If i plot the data with the logarithmic scale it gets pretty ugly, because i
have a lot of values which are zero,
which means on the log scale the value goes to -inf.
Here is an example what i mean

I acutally have no idea how to make the plot look better, 
maybe somebody has an idea ? 

thank you
