OK, I've created a QwtPlotCurve descendant, QwtPlotGappedCurve, with
virtual void draw(QPainter *p, const QwtScaleMap &xMap,
const QwtScaleMap &yMap, int from, int to) const
overridden and additional data member, gapValue.
Everybody interested in can see attachment.
Uwe, maybe it will be useful to include this class into Qwt package?![]()
