Labeling a curve

[kalgorithmist]

Hi,

I am new to Qt and Qwt. I want to set a label or a title for the plotted curve. I tried setting something like this:

QwtPlotCurve curve;
 
curve.setTitle("some curve");

QwtPlotCurve curve;

curve.setTitle("some curve");

To copy to clipboard, switch view to plain text mode 

but "some curve" is not shown.

Any ideas?

many thanks.
