I recently had to design a few reports using Birt.
Amongst some other newby problems, I had this one which I think is a Birt engine bug : when designing or rendering a bar char with long labels, the "ellipsis" thing doesn't work as expected and either the chart isn't displayed at all, or X axis labels aren't displayed.
To address this, you can use scripting to simply cut labels after a certain amount of characters and manually add ellipsis :
To do so, simply select your chart in the designer and switch to the Script tab. Then add the folowing code :
Hope this helps !

var cutLabel = ""; function afterDataSetFilled( series, dataSet, icsc ) { for (var i=0; i20) { // cut the string after 20 chars and add ellipsis dataSet.getValues()[i] = value.substring(0,20) + "..."; } } } function beforeDrawAxisTitle( axis, label, icsc ) { if( axis.isCategoryAxis() ){ label.getCaption().setValue(cutLabel); } }
Hope this helps !
