Legend text alignment via CSS?

[rmicalet]

Is it possible to align the text in the legend such that the series names are aligned to the left and the values are aligned to the right?

For example:

ABC: 23.1
DEFG: 317.2
HI: 6.7

Would be immensely grateful for any insight.

Those numbers didn't come out with the appropriate spaces. The attached figure shows the actual desired alignment.
