[Problem with LineChart]

I´m trying to display values above each point of my line chart but I have failed many times, I have tried with labelExpession Tag but it doesn´t work, a quick reference that I found means that this property only works with piechart.

 

I post the JXRML code down here...

 

thanks in advance...

Code:

<lineChart> <chart evaluationTime="Group" evaluationGroup="FirstLetterGroup" hyperlinkType="None">   <reportElement positionType="Float" x="0" y="25" width="270" height="175" backcolor="#FFFFFF"/>   <chartTitle color="#000000"/>   <chartSubtitle color="#000000"/>   <chartLegend textColor="#000000" backgroundColor="#FFFFFF"/> </chart><categoryDataset> <dataset resetType="Group" resetGroup="FirstLetterGroup" incrementType="Group" incrementGroup="CityGroup"/> <categorySeries>  <seriesExpression><![CDATA["Freight/Orders"]]></seriesExpression>  <categoryExpression><![CDATA[$F{ShipCity} + ", " +$F{ShipCountry}]]>    </categoryExpression>  <valueExpression><![CDATA[new Double($V{FreightSumCityGroup}.doubleValue() / $V{CityGroup_COUNT}.doubleValue())]]></valueExpression>  <labelExpression><![CDATA[$F{ShipCity}]]></labelExpression></categorySeries> </categoryDataset>	<linePlot>  	 <plot>	  <seriesColor seriesOrder="0" color="#0000CC"/>	</plot>								<valueAxisLabelExpression><![CDATA["Freight per Order"]]></valueAxisLabelExpression>								<valueAxisFormat>									<axisFormat labelColor="#0000CC" tickLabelColor="#0000CC" tickLabelMask="$#,##0" axisLineColor="#0000CC"/>								</valueAxisFormat>							</linePlot>						</lineChart>

[MultiAxisChartReport (sample chart)]

I have those problems too, I´m newer than you using Jasper report y JfreeChart.

 

I need you help, If you could send me all charts funtional examples that will be great.

 

My best regards, and thanks very much for your help.
