    Question How to reset zoom in/out back to original plot scale using QwtPlotMagnifier?

    I'm using QwtPlotMagnifier to zoom in/out, want to have a reset button to clear the zoom.

    Thanks in advance.

    QwtPlotMagnifier has no memory about the previous scale ranges. This is something you have to implement in application code.
