Thomas Gerbet (tgerbet)2021-04-22 13:37 Hello, Thanks for the report, some changes have been made in request #20940. You now get a message telling you to update your chart settings until you select a field: An error occurred while loading the chart: Unable to find the needed field to build the chart "Untitled cumulative_flow". Please edit the chart and adjust settings. It's not great but it's still far better than just having a technical error. The way the graphs are created would benefit from a complete revamp but for now I'm going with "good enough 🤷" and I'm going to close the request. Status changed from New to ClosedConnected artifacts Added Fixed in: rel #19725Close date set to 2021-04-22
