Detailed Description

Defines an appearance of QSCurve Base class.

Draws a single element of QSCurve. It can be reimplemented to draw Bars, Vectors, etc, see QSCurve::setPObject. startDrawing() is always called before the drawing begins, endDrawing() is called after drawing is finished. When drawing initPass() is called and next drawSegment() method is called for each datapoint, finally endPass() in invoked and this operation is repeated a few times ( as requested by startDraw() return value )..
