I would like to ask if there is a bug or am I doing something wrong in this routine: [image] [image] [image] [{"id":"e05046c10f4aed17","type":"group","z":"52913d9d3ee83890","name":"Graph - Deep Diver","style":{"label":true,"stroke":"#92d04f","fill":"#c8e7a7"},"nodes":["04eef0fecf3be776","56c7e5…

Which versions of node-red and node-red-dashboard are you using? Is the dashboard the latest? What browser/version are you using? Can you try a different browser? Open the browser developer console. Make the chart fail, do you see any errors in the console window?
