CFChart x-axis labels too wide. How to angle the labels?

I have created a wide bar chart using CFChart in CF10.

There are quite a few bars and the labels are too wide, causing some labels to not print.

Does anyone know exactly how to angle them at 45 degrees like most charting tools allow?

I am ok with changing the style for all CF charts to an angled label.

Or, have you solved this without setting the labels at an angle?

Thanks!
