Scaling QwtSpectogram respectively the Axes

[revellix]

Hi Community,

I want to make a QwtSpectrogram that shows me the pressure_distribution in a gas lubricated bearing. For a gas bearing with a quadratic geometry I get the following picture:



When I now change the geometry to be rectangular, I get:



I want the axes to scale themselves automatically to see the difference between the length and width. I changed the picture manually -> this is what I want it to look like:






Any suggestions ? I simply dont get it.

If this is about having a fixed aspect ratio: see QwtPlotRescaler.

Check the navigation example,

It' probably sometimes hard for native English speaker too. It would be a great support if a native speaker would check API and documentation and send me patches.
