I'm using QML for my charts, but I have been able to achieve updating the series without removing and recreating it...
Qt Code:
wavgSeries.remove(0); wavgSeries.append(appWin.wxMsec,appWin.wxWavg);To copy to clipboard, switch view to plain text mode
Basically, removing the first element in the series, then just appending a new one...
