Hi all, as you can see in the screenshot below, I have a chart (the lower one in the screenshot) which stops drawing data correctly / by intention (at about 12 o'clock in this example) but the X-axis is moving on. Is there a way to stop also moving the X-axis when not data is received? [grafik] T…

I don't think anyone is "reponsible" for fixing bugs, but we do seem to rely a lot on just a few core developers. One of the best things about Node-red is that those core developers often share their advice and knowledge in the forum. The procedure is to raise an issue on github, then anyone is f…

As far as I know the x-axis should not move if the chart is not receiving any messages, are you feeding in any null values? Add a debug to all nodes feeding into chart node to see if any messages are still coming in. a message will null value will move the chart on.

here are two work arounds to fix chart when you stop updating [{"id":"2b3c5960.1660f6","type":"inject","z":"252a67bcee0134e1","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"control","payload":"toggle","payloadType":"str","…

@E1cid Thank you, I will have a look on it as soon as I have enough time for it... Kind regards Thomas
