Table data plotted along with chart

[anjanas]

Hi

Is there any way to display the data plotted shown along with the chart. I need it as a separate table . Not as the item label in each plot in chart .

X Y Value
10 10 100
20 20 200
30 30 300
40 40 400
50 50 500

Is there any way to do it.. Please help

Just tell me if it is supported with jfree? Or anything like displaying a long text along with graph ?

Hi

As far as I knew ,we cannot get the data display beside the chart other than the labels and titles and subtitles.I also with the same issue.I dont know whether jfreecharts supports this feature.

You have to create a separate JPanel and display the data in there, probably using a JTable.

A couple of the demo programs display data in a separate table. I don't remember the names of the applicable demo, but if you run the demo program you'll find them there.

If you need the table to be part of the chart, you can use a nested BlockContainer with LabelBlocks. The example here uses the following approach:
The x values and y values are stored as LabelBlocks in two separate BlockContainers each having a ColumnArrangement.
These two BlockContainers are managed by a further main BlockContainer that has a FlowArrangement.
it is probably not the best approach. I tried to use a GridArrangement but that threw a "Not yet implemented" Exception .
Enjoy.
