matrix difference

Dear ROOTers,

I woulk like to visualize the difference of two matrices in log scale. The problem I have doing this are the negartive entries, which are the some how mapped to zero. Is it possible to have a "logarithmic" scale where both positive and negative bin contents are shown using two different color codes for their absolute values?

Thanks for your help,
