QwtPlotRenderer for multiple QwtPlot

[Uwe]

Find your own layout ( = bounding rectangles in paint device coordinates ) where you want to have your plots and use

void QwtPlotRenderer::render(QwtPlot *, QPainter *, const QRectF &rect) const

void QwtPlotRenderer::render(QwtPlot *, QPainter *, const QRectF &rect) const

To copy to clipboard, switch view to plain text mode 

renderTo and export() are only convenience APIs calculating a rectangle from the paint device metrics and calling in the end render(). Have a look at the implementation of these methods if you are unsure how to setup a QPainter to render a PDF document.
