Solution
Simple answer: Use QwtPlot::setAxisScale().
sorry for answering my own question.
Problem
I want to have a plotting widget in my Qt application. Qwt provides such a widget with QwtPlot. However, I can't find any way to only display a certain part of the complete range of my data. Specifically, I want to display spectrums with a frequency range from 0 to 2^14. For the GUI however, only the audible range from ~20-20k Hz is of significance, so I only want to display that part. Do you know of any way of telling QwtPlot to do that? Thank you for your answers.
