Axis controls for Date types are currently broken in the API. If they were working, though, you would use hAxis.gridlines.count to set the number of labels. There is a bug report on this here; you can "star" the issue to get updates on it.

Hello,

I'm trying to use date as a type on hAxis to have a month-based gridline, but it doesn't seem to be possible to display more than 3 months no matter the font / graph size. When displaying numbers instead this problem doesn't exist, so it does look as a bug when displaying dates.

Slanting text, specifying gridline count, showTextEvery, ... don't help.

Here's a short example below.

Can anyone help me out with this?

Thanks

Thanks.

Seeing it's an enhancement request, I suppose we can safely say it won't be improved anytime soon, though.

Hi Mischiew,

You are somewhat correct that individual enhancement requests tend to get lower priority, but we do try to take them into consideration as we plan our work priorities, and because we are not single-mindedly focusing on bug fixes, the accumulation of more requests in the same area will tend to get addressed sooner. So I would encourage everyone to squeak that wheel and post those enhancement requests.
