The Thistle::RadialAxis class provides a coordinate system for Thistle::RadialChart.
The Thistle::RadialAxis class provides a coordinate system that specifies each point uniquely in a Thistle::RadialChart by (X,Y) coordinates. It also paints the axis in the view.
| qreal centerHoleDiam | ( | ) | const |
Returns the diameter of the center hole.
See the Thistle::RadialChart representation.
|
virtual |
Returns the coordinates as a QPointF for the given value.
The axisNumber identifier specifies the axis to use (a Thistle::RadialChart uses an axis by row ).
Implements AbstractAxis.
|
virtual |
Returns the coordinates as a QRect for the given value.
This QRect will be used to paint an ellipse.
