Try setting the item margin:

Code: Select all

renderer.setItemMargin(0.5);

this doesn't seem to work.
i tried with much larger values for margin as well.
thanks for trying.

If you are using the CategoryAxis, you can set the maximum number of label lines like this

Code: Select all

categoryAxis.setMaximumCategoryLabelLines(2);

Now, the labels will use 2 lines instead of one.

Regards,
Priya

this is how i am getting my chart
JFreeChart chart = ChartFactory.createBarChart("MyChart","countryPreference","Volume",dataset,PlotOrientation.VERTICAL,true,false,false);

in the dataset
dataset.addValue(currentRow.getCol3(), "",currentRow.getCol1());

currentRow.getCol1() Value is displayed below each graph.
this get trimmed to a short text with "..." to indicate incomplete text.

i need full text here.

Did you try the suggestion about calling setMaximumCategoryLabelLines()? T hat's what I would have suggested. Also, you can try rotating the category labels by 90 degrees.

A tooltip is a small text item in a box that appears in a client app user interface when the mouse pointer hovers over something for a short time. The ChartPanel class will display tooltips for some of the items in a chart (such as the bars) if they've been configured in the renderer.

If you are a server-side developer, your users can also see these tooltips in a web browser if you create an HTML image map to go along with a chart image.
