Try a reboot and clearing the browser cache and refresh the browser page. If no joy then add a debug node showing what is going into the chart and see what it shows. If that looks ok then stop node red and start it in a terminal post the output here (copy/paste please rather than screenshot). When pasting click the `` button at the top of the text entry window and paste the log in. Also check the Developer Console in the browser and see if any errors shown. ---

It’s always a good idea to explain how you solved your issue so someone else can benefit in the future. Even if it was a “stupid” mistake (I can’t begin to count the number of those I've made) explaining the issue/solution could help someone else. ---
