Hi Uwe,

Before i send my implementation, i want to be make sure about something. As you said, the default behaviour of logScaled plotting starts at e-100. I want to know that whether i can set a range to the axis. For example, i want to plot between 10, 100 in x-axis.

Shortly, There is a setAxisScale method of QwtPlot. can i use this method after log scaled axis? i didnt try it yet. I just thought it. what do you think?

Thanks..
