Hello,

I have design the graph using Qwt libraries in which I have multiple curves.
And this graph is automatically replot itself as per the curves inputs, i.e. changes the X-Y scale of plot.

Now when I use QwtPlotZoomer, it has default zoomBase() as QRectF(0,0 1000x1000).
And during autoscale if I use my mouse key to go out of zoom stack it comes to the value of zoomBase. At this point my graph curve is hidden somewhere as its looks too small in this big scale.

So my intention to set zoomBase with the sale of autoScale of QwtPlot, so that when I came back of zoom then I should be at scale of autoScale, not at default scale.

Hope I'm able to explain my issue,

Thanks.
