QwtPlotRenderer and ExternalLegend position

[Uwe]

QwtPlotRenderer::render() doesn't include an external legend - instead you have to calculate the layout for the legend in your application code ( like you do it with the legend widget ) and call QwtPlotRenderer::renderLegend() manually.

Thanks for your reply. In my case the legend was indeed rendered although it was defined as ExternalLegend, is that a bug or did I misunderstand the expected behavior you describe?

I understand I can renderLegend separately but maybe I'm missing QPainter experience, could you please direct me to how I can modify my code to render the legend separately in a position of my choosing? (for example (100,100)) ?

Thanks as always for your attention and reply,
Frankie

Come on:

QPainter painter(&img);
renderer.render(plot, &painter, ... ); 
renderer.renderLegend( plot, &painter, QRectF( 100, 100, ..., ... ) );

QPainter painter(&img);
renderer.render(plot, &painter, ... ); 
renderer.renderLegend( plot, &painter, QRectF( 100, 100, ..., ... ) );
