How to attach png files to qwtplot

[Uwe]

How do you want to use your png files: somehow related to plot coordinates - or a label somewhere in a corner / like a watermark ) independent from the current ranges of the axis scales ?

QPixmap pixmap(":image");
 
QwtSymbol *symbol = new QwtSymbol;
symbol->setPixmap(pixmap);
 
QwtPlotMarker *marker = new QwtPlotMarker;
marker->setSymbol( symbol);
marker->attach(this);

QPixmap pixmap(":image");

QwtSymbol *symbol = new QwtSymbol;
symbol->setPixmap(pixmap);

QwtPlotMarker *marker = new QwtPlotMarker;
marker->setSymbol( symbol);
marker->attach(this);

To copy to clipboard, switch view to plain text mode 

this method works for attaching files(.png, jpeg ...)
