Will I get Metrics of the data I extracted before even though the datasource doesn't have that data

I am writing a script which will insert a large amount of data in my datasource for grafana every 10mins. Once grafana fetches that data and gets the metrics, I would be clearing the datasource and adding new data.
Will grafana still be able to display my previous data metrics along with the new data visualisation?


If the data isn’t in the data source, Grafana doesn’t know about it.


Ok thanks for the help here.
