Fantastic work. You figured it out. Thank you for your effort.
I really don’t don’t consider it resolved. I don’t have a fix to my real problem. It would be good to know if you have a list of plugins that might cause a problem. At least I would have a place to start.
I thought about it. But it is time-consuming. So QuickCharts is good enough for the time being.
I installed RJ QuickCharts plugin. It works for my needs right now but I don’t think it has the capabilities of Visualizer.
