Overlayed chart with 2 bar

[edu_neri]

Hi,

I'd like to create a barchart with 2 or more categories using XYplot, but when i add the 2nd category, it just get over the 1st one. How can I solve this to render like DefaultCategoryDataset? I'm not using DefaultCategoryDataset class because I want to write a linechart over the bars.

Perhaps ClusteredXYBarRenderer is what you need:

mkivinie thx man, that did the trick.

But now i'm facing another problem. I've mixed values of other old years and now i'm having another problem. He is priting the old years with months.

Is there any way to create categories using strings, instead of numbers or dates?

You can specify what format you want the dates to appear using this method

Code: Select all

public void setDateFormatOverride(java.text.DateFormat formatter)

Skunk,
Thx for reply, but I do not want to set same date to all data. The 1st 3 will appear only year and the other will have month.

You should be able to achieve that with a custom DateFormat implementation that is using either a default SimpleDateFormat or, if a specific condition is met, a second SimpleDateFormat.
