Hi md,
If I understand you correctly, you would like to live update the chart’s data, while the range selector keeps the original data?
The range selector must always contain the same data as that of the chart. If the chart is updated with new source, the range selector will be updated too. There is no workaround for this unfortunately.
I hope this answers your question. If you have any other doubts, please be sure to contact us again!
