Google Visualization Spacing

Question

I have a chart similar to the one below using the Google Visualization API. My problem is that on the right side of where the key is for this chart(where it says low, medium, high) there is too much white space. How can I get rid of this white space?

Answer 1

As a kind of work around I ended up just making the graph wider and using overflow:hidden on the containing Div. If anyone knows if the API allows to make the white space smaller please let me know.
