Qwt Plot not starting in origin

I use a Qwtplot to plot some data. Now, the axes are from 0-50 and 0-100. Unfortunately the bottom left corner of the canvas is not exactly at (0,0) but at (-0.1,-0.1) or something close. Is there any way to put it exactly at (0,0)?

void QwtPlot::setAxisScale  (   int     axisId,
    double  min,
    double  max,
    double  stepSize = 0 
    )

Try using the above function on both axis that aren't lining up properly. If it still has a gap of some sort, you could try setting the minimum to be just larger than zero, and see if it lines up better.

Hope that helps.
