Hi,

I have a QWT plot which shows only positive data values as a curve. I want autoscaling to be done since the values are not fixed in a range. But when autoscaling is enabled for y-left axis, then y-axis starts with negative values. how can i avoid this?

setAxisAutoScale(QwtPlot::yLeft,true);

I tried changing void QwtPlot::updateAxes() in my own class but facing issues because of d_axisData[axisId] private data.

Thanks
