Deleting Chart-Data (


im trying to delete my stored chart-data to reset my Chart. But somehow it does not work. I still get the chart with the last data after i restart node-red. Before deleting i block new incoming data.


 contextStorage: {
        default: {

store flow

delete flow


Use debug nodes to work out what is going wrong. If you need to log debug data from startup then configure the debug nodes to output to the console, then you will be able to see them in log when you start node-red.


i came aup with the idea that i block the data in the wrong place. So i change my flow and it works :sweat_smile:.

U dont even need to block new data. If you reset the chart the flow. gets reseted too.
