Raigo,
There are a lot of ways to do this, but try:
function beforeDrawAxisLabel( axis, label, context )
{
importPackage(Packages.org.eclipse.birt.chart.model.attribut e);
importPackage(Packages.java.text);
//LINEAR_LITERAL
//LOGARITHMIC_LITERAL
//TEXT_LITERAL
//DATE_TIME_LITERAL
if (axis.getType() == AxisType.DATE_TIME_LITERAL)
{
value = label.getCaption().getValue();
importPackage( Packages.java.io );
var dtf = new SimpleDateFormat("yy");
var dtf2 = new SimpleDateFormat("MM/dd");
var dt = new Date(value);
var fn1 = dtf2.format(dt);
if( fn1.toString() == "07/14" ){
var fn2 = dtf.format(dt);
label.getCaption().setValue(fn2);
}else{
label.getCaption().setValue("");
}
}
}
