Appropriate Drilldown from Summary Data

You can do this with something like this:

<module name="HiddenSearch" layoutPanel="panel_row1_col1" autoRun="true">
    <param name="search">index=summary report=top_client_ips | top clientip</param>
    <module name="HiddenChartFormatter">
        <param name="charting.chart">pie</param>
        <module name="FlashChart">
            <param name="height">250px</param>
            <param name="enableResize">false</param>
            <module name="HiddenSearch">
                <param name="search">sourcetype=access_combined clientip=$clientip$</param>
                <param name="earliest">-30d@d</param>
                <module name="ConvertToIntention">
                    <param name="settingToConvert">click.value</param>
                    <param name="intention">
                        <param name="name">stringreplace</param>
                        <param name="arg">
                            <param name="clientip">
                                <param name="value">$target$</param>
                            </param>
                        </param>
                    </param>
                    <module name="ViewRedirector">
                        <param name="viewTarget">flashtimeline</param>
                    </module>
                </module>
            </module>
        </module>
    </module>
</module>

The inner HiddenSearch is the search that is getting populated with the argument from the clicked area.
