Offsetting Qwt Plot Markers and adding symbols to Qwt Legend

[Mikhail K]

Thanks for quick reply. The code below works

class TrianglePen: public QwtSymbol
{
public:
    TrianglePen(QColor symbolColor, QSize symbolSize) : QwtSymbol(QwtSymbol::LTriangle, symbolColor, Qt::NoPen,symbolSize)
    {
    }
 
    virtual void renderSymbols( QPainter *painter, const QPointF *point, int numPoints ) const
    {
        double symbolWidth = this->size().width();
        painter->save();
        painter->translate(symbolWidth*0.5,0.0);
        QwtSymbol::renderSymbols(painter,point,numPoints);
        painter->restore();
    }
};

class TrianglePen: public QwtSymbol
{
public:
    TrianglePen(QColor symbolColor, QSize symbolSize) : QwtSymbol(QwtSymbol::LTriangle, symbolColor, Qt::NoPen,symbolSize)
    {
    }

    virtual void renderSymbols( QPainter *painter, const QPointF *point, int numPoints ) const
    {
        double symbolWidth = this->size().width();
        painter->save();
        painter->translate(symbolWidth*0.5,0.0);
        QwtSymbol::renderSymbols(painter,point,numPoints);
        painter->restore();
    }
};

To copy to clipboard, switch view to plain text mode 

Does exactly what I want, very satisfactory.

Best Regards,
Mikhail
