Legende with VerticalBarChart

[Eldar Lyn]

Hi,

i need to know if it's possible to change the horizontal legende and instead of having the value under the bar to have a text?

Thanks in advance

Do you mean the legend or the category axis?

[Eldar Lyn]

Yes, i need to rename it in order to present this graph like an histogram, for example:

First Bar -> 0-10
2nd Bar -> 11-20
3th bar -> 21-30

Assuming I understand you right, you just have to customize the CategoryDataset a bit. The categories are the "names" below the bars.
Create your own, e.g.:

public class GraphData extends AbstractSeriesDataset implements CategoryDataset

and implement some required functions, such as getCategories() which returns all the Strings or whatever you want to see below the bars.

Thx, i succeed of doing that i want, but i'm now facing an other problem: my bar are not sorted correctly, example:

Table
-------
Value || Id
12 || 1
16 || 2
23 || 3
29 || 4
16 || 5
12 || 6

My sql query is:
Select Id, Value from Table order by Id;

With SQL Plus, i've no problem, but when i draw the graph, it's completly mixed, like an order 2 - 3 - 5 - 1 - 6 - 4

Any ideas?
