QwtPlotRenderer for multiple QwtPlot

[Momergil]

Hello!

I'ld like to export to a pdf [using QwtPlotRender] various QwtPlot, not just one. How could I do that?

For now what I do is:

QwtPlotRenderer renderer;
renderer.exportTo( graphCandle, "test.pdf" );

QwtPlotRenderer renderer;
renderer.exportTo( graphCandle, "test.pdf" );

To copy to clipboard, switch view to plain text mode 

and I want to export other two QwtPlot besides graphCandle in the same .pdf.

Is there a way?

Thanks,

Momergil
