QwtPlot orthonormal visualization

[jomarin]

Hi everyone,

I am working on an application using QwtPlot displaying technical drawings. The issue is that I have to always keep the graph display orthonormal whatever the size of the visualization window.

Do you have any ideas of one good way to do this ?

Thanks in advance,

Joel Marin.

Maybe QwtPlotRescaler is what you are looking for.

Thanks Uwe for your fast reply.

I managed to force the visualization to be always orthonormal using QwtPlotRescaler.
Now, I try to print the generated drawings.

I used the method presented in the Bode example.
Is there a simple way to print the graph orthonormal ?

Now, the graph is expanding to A4 size.

Thanks in advance,

Joel.
