Display log of histogram in wxgui

[cgsbob]

Quite often, I deal with rasters with a wide range of values. When I view the histogram in the new wxgui, I am presented with a useless histogram. A log of the histogram would give me more useful.

I'm not sure in which version but the wx-based histogram tool (not d.histogram) has Log scale option for both axes.

Plot options (yellow wheel) > Plot settings > Axis settings > X-Axis > Log scale

The remaining issues are that d.histogram does not support this and that wx-based histogram tool might be replaced by matplotlib-based tool and the feature must be kept. Anyway, problem fixed, closing ticket.
