Gantt Chart: Zoom to a specific date/day

Hi everybody,

I have a question regarding the zoom operation in the chart panel.
Currently it is possible to drag a certain interval and the panel will automatically zoom into this interval.
How can I programmatically zoom to a specific date (java.util.Date) ?
Let say I have several tasks and sub tasks between 1.1.2007 and 1.12-2007.
I want the panel to zoom to the tasks of the current day when displayed.

Do somebody have any idea ?
Thanks a lot in advance.

This is from the javadoc for org.jfree.chart.axis.DateAxis

You will find it easier to understand how this axis works if you bear in mind that it really displays/measures integer (or long) data, where the integers are milliseconds since midnight, 1-Jan-1970.
