Try something like this: CategoryItemEntity categoryItem = (CategoryItemEntity)e.getEntity(); String selectedName = categoryItem.getColumnKey().toString(); That's for a category data plot. I'm sure it would be similar for other plots. Just see what type of Entity, e.getEntity is giving you and typec...

Is that Today bar part of your Gantt Chart? Is there a simple way to draw that on the Gantt Chart?

as long as the chart is put in a ChartPanel it'll redraw as you add data to the dataset.

Crap I didn't see the date, I was using the search tool and stumbled upon this thread while trying to find an answer to something else. Now don't I have egg on my face?

So it would take a large rewrite to get something like this working across a Category Axis?

Anyone have any ideas?

Try something similar to this. It has worked for me. public class SelectionEnabledGanttRenderer extends GanttRenderer { private int selectedRow=-1; private int selectedColumn=-1; @Override public Paint getItemPaint(int row, int column) { Paint p = super.getItemPaint(row, column); if(row==selectedRow...

I also want to record the x-y values. If you had a ChartMouseListener to the ChartPanel you can use the event: public void chartMouseClicked(ChartMouseEvent e) to get the x-y values for a clicked on item. XYItemEntity xyItem = (XYItemEntity)e.getEntity(); xyItem.getDataset().getX(xyItem.getSeriesIn...

Hi, The dataset type is unimportant... It's all about the axis. Since DateAxis is a ValueAxis you should be able to use the code without too much hassle, just remember to translate the BoundedRangeModel values to a valid date. How about scrolling across tasks in a Gantt Chart? That axis would be a ...

I would also like to know if this can be done, specifically in the vertical direction.

Presently, however it doesn't seem possible. There has been some discussion on this here and here. However I can't get either of these to work.

Alright, I'm trying to use this workaround but it doesn't seem to like dynamically adjusting itself. What you have described works upon initial creation but I'm adding new tasks dynamically. if(count > 40) { chartPanel.setRangeZoomable(true); chartPanel.setMinimumSize(new Dimension(chartPanel.getWid...

Actually I was looking for more of a solution with the sizing of the chart in a ScrollPane. I have a gantt chart that I would like to scroll along the Y axis and thought if a solution for scrolling this chart was found it would be applicable to my problem as well.

That appears to be very similar. I'll take a look at trying to fix that.

I appologize if this has been answered before but I need an answer. I'm making a TimeSeriesChart that keeps track of 3 days worth of data that comes in 8 hour increments (So 9 data points at a time) I have everything working except for the Domain axis: timeChart.getXYPlot().getDomainAxis().setFixedA...

I know this thread is pretty old but I had come across a similar problem and was wondering if a solution was resolved since this thread initially was created.
