Hello,  
I am using node-red in a docker container. The persistent data is stored outside the container in a named data volume. But the time series data from mqtt is lost every time the container is restarted. Is there a way to store this data as well, so that not all graphs are empty at every restart?

Thanks,  
Ralf

Welcome to the forum @polareisbaer

Are you storing the time series data, or are you relying on the chart to keep the data?

Hello,  
I keep the data only in the chart. So I want to keep the charts.

This should help. [Simple save and restore for node-red-dashboard chart (flow) - Node-RED](https://flows.nodered.org/flow/92920b4fd450bf92a3035e061947daa0)

Of course, there are many ways to do this in Node-RED. Colin showed 1 but you could equally set up a file-based context store and use that instead.
