    Default How to scale a curve

    I have a realtime plot with many curves having different range of values. One has range from 1000 to 10000 and other from 0.1 to 2 for example.

    How can I scale a curve so that they would be drawn close together?

    Also is it possible to draw several y axis next to each other? Thanks.

    Is the only way to scale y-values before drawing a curve to multiply all y-values with some factor ?

    You could also overload QwtPlotCurve::drawSeries, where you manipulate the scale maps.
