QwtPlot reset (clear samples)

[gaminn]

Hello,
how to delete all data from QwtPlotItems attached to QwtPlot? I need to reset my QwtPlot so there is nothing plotted on it.

Thank you

Martin

See example realtime.There they have added a functionality for clear.

QwtPlot is derived from QwtPlotDict. How to "clear" a plot item depends on the type of plot item, f.e. for QwtPlotCurve simply assign data without points.
