autoScale doesn't work

[Braunstein]

Hi,

I cannot see where my code influence the autoscaling. I only create a curve, attach the curve to the plot and then add data by using

m_curve->setRawData(&x[0], &y[0], std::min(x.size(), y.size()));

m_curve->setRawData(&x[0], &y[0], std::min(x.size(), y.size()));

To copy to clipboard, switch view to plain text mode 

x and y are vector<double>.
Of course there are more code. But this should have no effect to this.
The same code works fine with older versions of qwt.
