How to create a radio button for chart type?

[chadman]

I'm trying to create a radio button for chart type, but it's not working. All my charts are coming up column regardless of the radio button selection. Here is how I have the radio button setup.

   <input type="radio" token="charttype" searchWhenChanged="true">
      <label>Chart Type</label>

      <!-- Define the default value -->
      <default>Area</default>

      <!-- Hard-code the choices -->
      <choice value="column">Column</choice>
      <choice value="area">Area</choice>
      <choice value="line">Line</choice> 
    </input>

And I have the chart set up like this:

      <title>Internal Ping Time</title>
      <option name="charting.axisTitleX.text">Date</option>
       <option name="charting.axisTitleY.text">Ping Time (ms)</option>
      <option name="charting.chart">$charttype$</option>
      <option name="charting.primaryAxisTitle.text"/>

*UPDATED*

I don't believe you can do that. However, you can have three different panels, each with specific chart types and show/hide them based on user selection. Something like this

<input type="radio" token="charttype" searchWhenChanged="true">
    <label>Chart Type</label>

    <!-- Define the default value -->
    <default>Area</default>

    <!-- Hard-code the choices -->
    <choice value="column">Column</choice>
    <choice value="area">Area</choice>
    <choice value="line">Line</choice>
    <change>
        <condition label="Area">
            <set token="area"></set>
            <unset token="column"></unset>
            <unset token="line"></unset>
        </condition>
        <condition label="Column">
            <set token="column"></set>
            <unset token="area"></unset>
            <unset token="line"></unset>
        </condition>
        <condition label="Line">
            <set token="line"></set>
            <unset token="column"></unset>
            <unset token="area"></unset>
        </condition>
    </change>
</input>

.....
<row>
    <panel depends="$area$">
        <search>
            <query> ... | eval x="$area$" | ...
            </query>
        </search>
        <chart>
             <option name="charting.chart">Area</option>
        </chart>
    </panel>
    <panel depends="$line$">
        <search>
            <query> ... | eval x="$line$" | ...
            </query>
        </search>
        <chart>
             <option name="charting.chart">Line</option>
        </chart>
    </panel>
    <panel depends="$column$">
        <search>
            <query> ... | eval x="$column$" | ...
            </query>
        </search>
        <chart>
             <option name="charting.chart">Column</option>
        </chart>
    </panel>
</row>

The reason for the eval x=$area$ etc. in the query is to prevent that search from executing when not needed.

Thanks and I tried that, but I get this error:

XML Syntax Error: Cannot find object mapper for panel type: panel

I'm using version 5 of Splunk.

See the updated version. The token name for the depends attributes needs be within $ symbols. Although I do not know if this will work in version 5.

I still get the same error, but we plan to upgrade to a newer version by the end of next month. I'll give it a try then. Thanks for the help. Chad
