Hi,

I have been trying to avoid crying for help since I thought I was going to be able to implement my waterfall like plot using QwtPlotSpectrogram but things are not going as planned!

I need to plot horizontal bars in which each bar is divided into squares according to the number of variables that I receive externally. What I need is that each square will have a precise color according to a colour map and not according to some kind of interpolation between the points!

So far I have tried using QwtSpectrogram with no luck and (as suggested in another thread) QwtPlotSpectroCurve with a bit more success but while the y-dimension of my squares are ok (I am using a big PendWidth) I can't manage to change the 'dimension' of the x coordinate for each square.

Thanks in advance.
