Hi,
I got a radchartview with some scatterlineseries. When the user changes a parameter, the chart should be updated with a new series. That works but the old series is still on it. I tried radchartview.series.clear, but I would need something to clear/reset the whole chart before adding the new series.
How can i do that, please.

I have tried this with a pie chart, and I can't delete the 'old' image (User experience means that the old chart image is no longer valid, and user expects to see an empty space, not the old pie chart)
Any more suggestions?

Hi Ian,
If you are not adding another series you will need to invalidate the chart:
