Is something like that possible?

Not possible. The chart is rendered client side (in a browser) everything else (including telegram) is server side (in node-red).

There are a bunch of if, but IF you are running on a linux device (like a Pi) AND you are storing the data so it can be retrieved:

You can instal gnuplot and create an ascii plot and save it as a file. Then send the image via telegram.

Here is a flow that creates a plot every two hours that you can try out (you will have to modify)

Merci @zenofmud
yes it is a Pi and local stored in influxDB!
and i will have to install the sqlnode too.
how did you add this colored background?

have a nice day

You should keep up with the blog and relase notes :wink: Version 1.1 released : Node-RED
