Steering Wheel Chart Data Label Size. How do I change the size?

Hi,

I've put together a donut chart to represent data in a traffic light system. I have made a function to take my data and change the colours of the segments.

My problem is that the data labels bound boxes are too small. How can I change these? If text boxes are the only option is there a neater way to rotate these over then dragging the rotate handle?

minor improvements attached....
you can increase size by increasing Font size and turning off Word Wrap
you will need to move individual data labels because they are no longer readable

however at the end of the day you really only have so much real estate to work with
especially with long labels like
Scanned Dispatch
Fulfilment Inc. SDF
Fulfilment
Negative Balances

you might want to consider acronym them like FTE
