How to show dynamically chart title ?

[sieutruc]

Hello,

i have a xml as:

   module name="Pulldown" layoutPanel="panel_row1_col1" autorun="True"
    param name="name">latency   param
    param name="label"> Type of Latency  param
    param name="staticOptions"
.....
    module name="HiddenChartFormatter"
       param name="chartTitle"> Machines' "$latency.label$"  param

Here, it doesn't show the value referenced by $latency.label$, instead is "$latency.label$". How to show dynamically chart title basing on chosen option of Pulldown module ?

HiddenChartFormatter is not a Sideview module, but rather a core Splunk module. As such I'm afraid HiddenChartFormatter does not do any $foo$ replacement. Very few of the core Splunk modules do.

1) However you can easily use the ValueSetter module to do the same thing. Here we use the ValueSetter to take our label key from the Pulldown, and translate it into a 'charting.chartTitle' key that will be recognized by the charting module.

<module name="ValueSetter">
  <param name="name">charting.chartTitle</param>
  <param name="value">Machines' "$latency.label$"</param>

2) Perhaps better, because the FlashChart and JSChart module's internal titles can be a little pokey to use anyway, is instead of using ValueSetter as a sort of adapter between Pulldown and FlashChart, just use an HTML module to make your own header. Put this HTML module downstream from the Pulldown and just above the FlashChart as a sibling of the FlashChart:

<module name="HTML">
  <param name="html"><![CDATA[
    <h2>Machines' "$latency.label$"</h2>
  ]]></param>
</module>
