SubDataSet in chart with Parameter

[micmayers_i]

Hello

I´ve found following code for using subDataset in Charts.

This Code is working without the parameter.

My Question now is, how to pass the parameter to the JRXmlDataSource.

Thanks very much

Code:

<lineChart><chart>...</chart><categoryDataset><dataset>	<datasetRun subDataset="Parameter">		<datasetParameter name="param">			<datasetParameterExpression></datasetParameterExpression>		</datasetParameter>		<dataSourceExpression><![CDATA[new   net.sf.jasperreports.engine.data.JRXmlDataSource(new java.io.File("C:\\test.xml"),  "/test[@id='$P{param}']/tested")]]>		</dataSourceExpression>	</datasetRun></dataset>

Should be able to righ click the sub-dataset in the report inspector and bring up the properties, within there if I recall is a parameter mapping section which allows you to map parameters in the sub-dataset from the calling report.

Select the chart -> right click option "Chart data" -> Tab parameters (under drop down box "Sub dataset"

Hy

dosen´t works with the part 

"[@id=$P{param}]"

doesen´t matter which settings I tried in the parameter Tab (under drop down box "Sub dataset").

Mayby you can tell me a bit more explicite how to set the parameter for the dataSourceExpression.

Thanks mic
