How to plot a bar chart (chart is getting data from sub dataset) with huge numbers of data points (more than thousands) in multiple pages

[anamika.rimpi]

Hi, 

I want to plot a Bar chart in multiple pages as the dataset is huge (more than 1000 points).

The chart needs to use a java bean data source.Below is the jrxml code for the chart for getting data.

One parameter has been created.

<parameter name="datasource4" class="java.util.List" isForPrompting="false"/>

Then one dataset has been created.

<subDataset name="dataset4" uuid="8424528c-d095-4b51-9e08-d6346bef037f">
        <field name="name" class="java.lang.String"/>
        <field name="count" class="java.lang.String"/>
    </subDataset>

Below is how chart data is getting assigned.

<categoryDataset>
                    <dataset>
                        <datasetRun subDataset="dataset4">
                            <dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($P{datasource4})]]></dataSourceExpression>
                        </datasetRun>
                    </dataset>
                    <categorySeries>
                        <seriesExpression><![CDATA[$F{name}]]></seriesExpression>
                        <categoryExpression><![CDATA[$F{name}]]></categoryExpression>
                        <valueExpression><![CDATA[integer.parseInt($F{count})]]></valueExpression>
                    </categorySeries>

</categoryDataset>

I want to use group (lets say splitter) with this chart to split the chart in multiple pages, which is not allowed.

Please suggest how can I use group for chart with subdataset.

Thanks,

Anamika
