    Cool Re: QwtPlotMarker example

    Qt Code:
    1. QwtSymbol *sym=new QwtSymbol(QwtSymbol::Diamond,QBrush(Qt::red),QPen(Qt::red),QSize(5,5));
    2. mark->setSymbol(sym);
    3. mark->setValue(x,y);//here you have to set the coordinate axis i.e. where the axis are meeting.
    4. mark->attach(yourplot);
    To copy to clipboard, switch view to plain text mode
