I found this method to solve this problem.
QPixmap pixmap("myPic");
QMatrix rm;
rm.rotate(angle);
pixmap = pixmap.transformed(rm);
QwtPlotMarker *marker = new QwtPlotMarker;
marker->setSymbol( symbol);
marker->attach(myPlot);
Question
I want to rotate my marker in my plot but i cant. Here is my code to adding images to plot:
QPixmap pixmap("myImage");
QwtSymbol *symbol = new QwtSymbol;
symbol->setPixmap(pixmap);
marker = new QwtPlotMarker;
marker->setSymbol( symbol);
marker->attach(this);
I tried to rotate with QTransform but i couldnt achive. Is there any trick to solve this problem?
Thanks.
