JasperStudio How to use conditional style?

问题

I am desperately trying to format the Field "FilmID" based on it's value. Could you provide me with a conditional expression to format values >= 3 in red color ?

Conditional Style

Thanks a lot in advance!

Another variant of this question would be, what did I do wrong in this expression:

<style name="Style1" mode="Opaque" backcolor="#DBD82A">
        <conditionalStyle>
            <conditionExpression><![CDATA[$F{Revenue} > 10000]]></conditionExpression>
            <style mode="Opaque" backcolor="#C92B28"/>
        </conditionalStyle>
    </style>

回答1:

Assuming that $F{Revenue} is numeric (Integer, Double, Float ecc)

if you are using jasper report version 6.0 or above there is nothing wrong with your style expression, for jasper report 3.0, you need new Boolean($F{Revenue} > 10000)in expression.

You need also to be sure that you apply the style to a report element.

<reportElement style="style1" x="49" y="4" width="100" height="20" uuid="865e11e4-c2d4-40ac-be06-dc1359dc93c0"/>
