QwtPlot - detect zoom

[gaminn]

Hello,
is there a way to detect that QwtPlot has been zoomed by user using his mouse scroll wheel? I need to dynamically recalculate some values of currently visible part of graph's curves.

Thank you

Martin

Use mouse event(QWheelEvent) to check and check it only on that plot.
