QwtPolar - Title for Radius Axis

[Crowley]

Hello,

is it possible in QwtPolar to set a title/unit for the axes (at least for the radius axis)? Unlike QwtPlot, QwtPolarPlot misses methods like setAxisTitle(...)
I'm using QwtPolar 1.0.1.

QwtPolarMarker() should work.

As a workaround, ok. I am using it (seeing no alternative). But re-positioning for changes in the scale has to be done all "manually" then.

I would derive from QwtScaleDraw and overload one of its virtual methods, adding the QPainter::drawText() call you need. F.e:

class YourRadiusScaleDraw: public QwtScaleDraw
{
   ...
protected:
    virtiual void drawBackbone( QPainter *painter ) const
    {
        QwtScaleDraw::drawBackbone( painter );
 
        // now calculate the position/alignment/rotation for your text and
        // do the painter->:drawText() call
        ...
    }
};

class YourRadiusScaleDraw: public QwtScaleDraw
{
   ...
protected:
    virtiual void drawBackbone( QPainter *painter ) const
    {
        QwtScaleDraw::drawBackbone( painter );

        // now calculate the position/alignment/rotation for your text and
        // do the painter->:drawText() call
        ...
    }
};
