qwt

I'm using Qwt for some scientific graphing, and I'm working with some fairly small numbers, the smallest being around 1.0e-22.

I'm trying to call

setAxisScale(xaxis, xmin, xmax) //xmin = 0, xmax = 2.0e-10

But when I do, the application locks up. I haven't found anything in the documentation that refers to a minimum value. Xmin and xmax are both doubles, so that shouldn't be a problem.

Is this a bug in Qwt, or am I doing something wrong?

Thanks in advance
