Stacked and Adjacent bars?

[casesolved-co-uk]

Is it possible to have both stacked and adjacent bars on the same chart?

The BarOptions have the option of one or the other.

An example is below; is it possible to have the previous year displayed next to the the current year for comparison?
I realise the labels would need to be the same, i.e. Jan, Feb, Mar... rather than having the year in there creating separate labels.
