Modify Graphs using CSS

Hello Design Studio gurus,

I have been trying unsuccessfully, for the last couple of days, to modify the style of a bar chart by using a Custom CSS in Design Studio 1.2.

What I am after is:

- Changing the font and size of labels in both axis of the chart

- Changing the font and size of values in both axis of the chart

Any pointers in the right direction will be greatly appreciated
