Chart update not working

Hello I have trouble with showing values on chart. Chart is empty. I run out of ideas.

Point is one of 3000. y value goes to 10 and x value is time from 0:0:0 to 23:59:59

{"x":"14:46:48","y":0}

Please indicate via the thread's tags whether this is for Dashboard 1 or 2. Thanks.

@Sekuti's screen capture shows Class and Name at the bottom of the popup, thus it's the original, node-red-dashboard.

The original dashboard is picky about it's input data structure.
Can you capture the entire message payload (using a Write file node?), edit it, deleting about 2995 of the 3000 data points before sharing it here?
