Display Mirror Column Status Summary in Dashboard Chart Widget


I’m trying to make a chart for a mirror column which has the summary of the status of items from connected boards, however I cannot find a way to do so.

For clarity, the diagram below shows what I’m trying to accomplish:

I understand that this can be done using a subitem status summary column but is there anyway to do this using a mirror column? If not, is there anything similar I could do to display the mirror column in a widget?

Thank you!
