Pivot Chart without tables - Ordering bar chart

[MadHatsJess]

Hi

Hoping some genius can help!

I have some Pivot Charts (Bar chart) that come from data within the data model.

I need to move the bars as they are not in date order. They should be November, December, January but they are in A-Z.

Usually if there was a pivot table I would move around the dates and the graph would update but as there are no pivot tables I am lost!

Is there a way to do this?

I really don't want to have to go back to running pivot charts from tables.

Thanks

Jess
