Wrapping Labels in Charts

lgudait

Hi,

I'm trying to create a bar chart, and the values for the labels in the x-axis are fairly long. I would like to wrap the text on the x-axis so that all of the values are shown; changing the angle to fit everything in isn't sufficient, as this makes the plot area of the graph too small on the report.

Is there a simple solution that I may be missing?

You could use regex in the beforeDrawAxisLabel() to split the labels into new lines every n characters doing something like this.<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>importPackage(Packages.java.lang);
importPackage(Packages.java.util);
importPackage(Packages.org.eclipse.birt.chart.model.attribute);

function beforeDrawAxisLabel( axis, label, icsc )
{
if(axis.getType() == AxisType.TEXT_LITERAL) {
var currentLabel = label.getCaption().getValue();
var parsedLabel = currentLabel.replaceAll("(.{3})", "$1\n"); // New line every 3 characters

label.getCaption().setValue(parsedLabel)
}
}
</pre>
<br />
This will split the labels every 3 characters. You can view the chart but the label will still be cut off. To fix this open up your chart UI > chart area > outline. You can adjust the bottom inset here. The larger the number the more room you will have for your labels.
