I am trying to chart multiple years with multiple data
ie 2 yrs each with 2 business units, each having GM & OP

i want all GM to be bars & all OP to be lines. Excell automatically does
this, but not how i would like

Select the series you want to change and right click on it. You should see
an option for Chart Type. Change from Line to Bar or vice versa.
