Turn on vertical grid lines between tick units?

[Erich Kilmer]

I am creating time series charts with ranges of less than 30 days.
JFreeCharts auto tick selection does a nice job of selecting the right tick unit so that the tick labels fit at the bottom and do not overlap.
When I display 30 days of data (notice 1 point per day) it selects a tick unit of 7 days. This looks fine.
Is there any way to turn on the vertical grid between the tick units?
I would like to have vertical lines for each date (not labels) between the tick units.
Thanks!

Right now the grid lines are only drawn at the same points as the tick marks/labels. Eventually, I'd like the axes to support major/minor tick marks, and the same for the grid...but that is some way down my list of priorities. Someone else may implement it before I get to it, though.

OK. I appreciate the response.
