Hello, community! I need your help.
How can I plot a line graph using the Chart.js library. It is necessary to display a graph of temperature ("System1:Conveer.Motor1.Temperature:_online.._value") versus time.
Thank you.

Hello.
e.g. when you use NGA you can connect to influxDB and operate data like with any other db.
Of course you need backend.

Look into the webview ewo javascript interface under Graphics editor (GEDI) -> Complex graphics objects -> EWO (External Widget Object) -> WebView EWO -> JavaScript Interface Examples.
There is an example to plot a graph with a javascript library.
