I have discovered functionality to switch series (lines) on/off by mouse click on to the legend square in the chart head (see the orange line/legend on the charts below).

Unfortunately, the change is not persistent. After 15 seconds approximately the series returns to its default.

Is there a way how to made the change persistent?

are you redrawing the complete graph ? or just adding data to it ?

Not understand your question really. I am feeding standard dashboard graph node with 5 inputs msg.topic=series name (displayed on the top of the chart with small square), msg.timestamp=timestamp, msg.payload=temp.

I would like to change the on/off topic timing.
