I have created a program that plots the results into a colour map. It works fine, but when I change the colour map's scale to logarithmic (otherwise I can't see much), the legend looks very odd, with values shown at linear intervals (because the scale is logarithmic, they are all massed on the top). If I set both the QCPColorScale and QCPColorMap's data scale type to logarithmic, it still persists. I am using a version that I have downloaded quite recently.
Here is a screenshot of what it does:
Am I doing something wrong or there is a bug?
