    Default qwp plot axis scale

    hey,

    i have a problem scaling my plot. i want to create a zoomable and moveable plot but that QwtPlot::setAxisScale() function doesnt seem to work.
    if i use it, the scale on my axis doesnt change at all, and the plot is just reduced to one dimension (all the points lying on that axis are drawn in a straight line). I cant really figure out how to use it. do i have to use it at a certain point in my code or do i have to repaint the plot and the axis somehow after using it?

    thanks!

    well nevermind...
    im still figuring out the basics and a simple "replot()" was enough.
