Hello.

I have a few questions about these two similar classes.
Is there a way to either:
a) display X or Y axis on a logarithmic scale,
b) change the labels of the ticks?

These options seem viable for basic XY plots, but I haven't found a way to utilize them with QwtRasterData/QwtMatrixRasterData.
I want to plot a series of 3D data with a very large Y scale, so I want to either plot it in a logarithmic (or a semi-logarithmic) scale or to simply recalculate my Y axis values (newY=LogStartPoint+LogStartPoint*log10(dataPoint/LogStartPoint)) and to plot them in a linear scale with relabeled axis ticks.
