Node Red charts on DashBoard

General

Hi All, I am running a chart on my dashboard which is representing the output of sensor via MQTT.

It is all working well. My question to the forum is :-

Is the data which is being plotted in the chart accessible on the raspberry pi and if so, is it usable and can it be read as text??

If you are sending it to Dashboard then, by definition, it must be available in Node-RED on the Pi since that's where you sent it from.

If you want to access it outside of Node-RED, simply write it to a file or a db like SQLite.

Or pick it up from mqtt direct into whatever other app you want it.
