Any chart is not allow into accordian widget group

Hello All,   I am getting “Widget Accordion 'accordion1' cannot contain widgets of type any chart” error message when putting any chart widget into Accordian group.

Creators of the accordion have most likely not been aware that Accordion was unable to contain the AnyChart-widget until some time later when some user eventually tried it. And they have not been able to (find time to) solve this. So I guess your only options are to either not do this, or resolve the issue yourself by modifying the Accordion-widget, or ask the creators to do so. There are no other ways around it, unfortunately.
