How can i put axis units in the middle with correct Gridline

[Rahan]

Hello,

i have a TimeSeries Chart like this


The Problem: The month January is on the end of the scale. This confused the people who watch it too much.

I set the align with the command:
DateAxis axis = (DateAxis)plot.getDomainAxis();
axis.setTickUnit(new DateTickUnit(DateTickUnit.MONTH, 1, null));
axis.setTickMarkPosition(DateTickMarkPosition.MIDDLE);

axis.setDateFormatOverride(new SimpleDateFormat("MMM"));

Than i have something like this:




But the Gridline does not begin with the 1 Jan.
Can anyone help me, to create a TimeSeries like this fake

You won't get the result you want with a DateAxis, but the PeriodAxis class might work.
