I’m using Qwt 6.3.0 together with QT 6.7.2 to plot some live data with QwtPlot/QwtPlotCurve. At the moment, the data is stored in a fixed size array and gets cyclically overwritten.
In fixed intervals (10ms or something like), I trigger a “replot” on the QwtPlot which should also rescale (=UpdateAxes()) if I’m getting that right from the docs.
