Bar chart with 3 sets of data, 2 stacked

[Ironman]

Hello

I have 3 data series:

Series 1 is monthly Average values 2010-2019
Series 2 is monthly values from 2019
Series 3 is monthly values 2020 to date

I am trying to display all 3 series on the X axis, with Series 1 and 2 as stacked bars and Series 3 as a bar to the right of Series 1 and 2 and I can't find a template that will allow me to do this.

I would be very grateful for some help.

Thank you.
