I'm new to JasperReports. I'm designing a report using iReport. I have three values x,y,z. If z < y then the data color for z should be changed to 'black' & if z > x then data color of z should be changed to 'red'. Please tell me how to do it.
I am using JDeveloper to develop desktop app. and iReport to design JasperReport.
You can use Conditional styles
for solving this issue.
The sample:
<style name="ZFieldStyle">
<conditionalStyle>
<conditionExpression><![CDATA[$F{Z} < $F{Y}]]></conditionExpression>
<style forecolor="#000000"/>
</conditionalStyle>
<conditionalStyle>
<conditionExpression><![CDATA[$F{Z}>$F{X}]]></conditionExpression>
<style forecolor="#FF0000"/>
</conditionalStyle>
</style>
...
<field name="X" class="java.lang.Integer"/>
<field name="Y" class="java.lang.Integer"/>
<field name="Z" class="java.lang.Integer"/>
...
<textField>
<reportElement style="ZFieldStyle" x="200" y="0" width="100" height="20"/>
<textElement/>
<textFieldExpression><![CDATA[$F{Z}]]></textFieldExpression>
</textField>
