Sorting Graphs in descending order

Hi everyone.

I'm wondering if it's possible for us to sort dashboard graphs in descending order.

I've been told it is not an out the box functionality of Sage CRM but I assumed this to be a standard function? For example, I would like to be able to sort the below graph into descending order.

I've had a play around on the report itself and sorted the results into descending order but this does not sort the graph in size order.

Many thanks in advance.
