JFreechart set String value and/or Symbol to Xaxis

Question

I have a chart whose data are obtained from the database and the client now needs to be symbols printed below the X axis in the curve peaks. I tried something like NumberAxis.createIntegerTickUnits() method, but to no avail. How do I replace the values of the X axis by the symbols?

The needed chart is this:

I need on the axis setting the standardTickUnits on domainAxis. I've tried to insert an image to show the needed result on the post but this is my first question. — Rogerio A. Valente, Dec 04 '14 at 10:27
Have you looked at `SymbolAxis`? Upload a picture to `imgur.com`, and edit your question to include the link and your [code](http://stackoverflow.com/help/mcve). — Catalina Island, Dec 04 '14 at 11:37

@CatalinaIsland I've tried SymbolAxis. Maybe did something wrong. Tried to edit question and include link to image on imgur.com but the system "says" that I need 10 reputations to post image. — Rogerio A. Valente, Dec 04 '14 at 16:47

@trashgod the labels (symbols) on the curve is more easiest to implement? — Rogerio A. Valente, Dec 04 '14 at 17:19

Depending on the desired effect,

Consider using a SymbolAxis, illustrated here on the range axis.
Consider using an XYItemLabelGenerator, illustrated here.

Your tip worked very well. I made an adaptation of LabelGenerator class and I did not use the LabeledXYDataset class. We chose to put the symbols on the graph curve. Anyway, thank you so much. – Rogerio A. Valente Dec 05 '14 at 18:45
