I use: - DefaultTableXYDataset - StackedXYBarRenderer - XYPlot - XYSeries XYSeries method: - clear() does not work properly (there still remain all Items with null values) - add(x,y) does not work properly beacuse of: Exception in thread "AWT-EventQueue-0" org.jfree.data.general.SeriesException: X-v...

What is the formula to calculate the next auto color??

I use jfreechart 1.0.8 and removeDomainMarker is not working.

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

I use: XYSeriesCollection DATASET XYSeries SERIES The chart displays dataset correctly. I check values of series as follows: for i DATASET .getSeries(0).getDataItem(i).getY() and it shows the same values of SERIES that was set. Next step is updating my series, I tried two ways: DATASET.getSeries(0)....

Hi,my problem is that

I use XYSeries, and when I call update method it doesn't update my chart?

How can I update my chart with XYSeries on dataset?

Hi, I use XYSeriesCollection and how can I get a serie from dataset by serie's name ???

Thanks,

Some of charts provide 'an outlook' of values while I put cursor at them, and some don't.

It depends on dataset? or it can work for all charts?

Thank you! It works!

Please answer my question,

how is it possible to call method Print exactly the same from PopupMenu.

How to do that, the X-axis is not a string category, but like a integer values.

for example I have a values:
as points (x,y):

(1,10) (2, 14) (5, 9) (8, 4)

and I want to present that as bar chart. (4 bars)

Thanks
