Question on horizontal display

[Artemis]

Hi ,

I am creating a time-series chart using JFreeChart-0.9.3.
I just want to display the date in the horizontal axis for every day.
How can I get this done with 0.9.3 ?

Thanks so much.

In 0.9.3, you could call the setTickUnit(...) method on the DateAxis and pass it a DateUnit object. The DateUnit could be constructed like this to represent one day:

DateUnit unit = new DateUnit(Calendar.DATE, 1);

This has changed in 0.9.4 to work the same way as the NumberAxis tick units.

Thanks DG,

I got every day is displayed but the date is overlapped.
How can I make the date displayed vertically to avoid the overlapping ?

Thanks so much.

Hi Artemis,

I think it is something like this:

XYPlot plot = myChart.getXYPlot();
HorizontalDateAxis axis = (HorizontalDateAxis) plot.getDomainAxis();
axis.setVerticalTickLabels (true);
