Do you mean you want the yaxis to be the "log scale" of the data your are plotting in the plot? The difficulty of doing this with imshow() is that the structure in y is fundamentally linear, that is, imshow just shows everything as it's structured in the dataset.
A hack would be to simply copy more data into the plot in such a way that the data reflects a log distribution, so the "lower values" are weighted within the set.
Another track to take would be to try a meshgrid approach, this answer for a different question may help there:

this is exactly what i thought. I should duplicate the rows exponentially. Thank you for the response. – Mojtaba Nov 23 '12 at 17:18
