data label in bar chart

[brevleq]

Hi guys.

How can I show the value of a bar in top of them??
I've tried these tags, but nothing happened:

<expression name="field_nameChart" class="org.pentaho.plugin.jfreereport.reportcharts .BarChartExpression">
<properties>
<property name="categoricalLabelFormat">{2}</property>
</properties>
</expression>

Could someone help me??

<property name="itemsLabelVisible">true</property>

I've tried you code but the result is the same!
Here is my xaction file. Perhaps I forget put something...

I don't know too much about charts and I am also still struggling with it but maybe you could try setting all of the properties like...

<expression name="field_nameChart" class="org.pentaho.plugin.jfreereport.reportcharts  .BarChartExpression">  
            <properties>
              <property name="rangeStickyZero" class="java.lang.Boolean">false</property>
