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>

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.
