Line Chart: Missing commas when hover over points

[Brandon]

When you hover over a point on a line chart, the number doesn't have a
comma formatting. It isn't a huge deal if you have smaller numbers,
but when you are in the 200 million range it is tough to read. Here is
a screen shot.

I tried adding commas to the numbers and this causes an error because
it's not a real number:
data.setValue(i, 1, '100,100,123');

It has to be set as:
data.setValue(i, 1, '100100123');

The y axis does format the numbers, it's just the hover that doesn't
format the numbers.

Is this an option that I am missing or is this a bug?
