I've looked into doing that sort of thing (digging into the chart SVG code to find and modify particular elements) and it's not pretty. I've yet to find any method that works consistently across more than one type of chart, and often times it's hard to make the same method work for two different charts of the same type. It's doable if you know *exactly* what you are looking for (examining the SVG code in something like the Google Chrome developer console helps a great deal in this regard). Using jQuery to access the contents of the iframe and SVG also helps immensely.
