How to mark the highest and lowest values on a line graph?

[markthompson]

Hello,
I'd like to put an extra point on top of the highest and lowest values on a line graph, has anyone got any suggestions?

Hi markthompson,

take a look at the maxSpotColor and minSpotColor here in the docs http://docs.splunk.com/Documentation/Splunk/6.2.1/Viz/PanelreferenceforSimplifiedXML

Hope that helps ...

cheers, MuS

Hi MuS,
Thanks for that, so would it just be chart maxSpotColor = ??

Then is it a hex value, or how should it be displayed?

This from the dashboard example app https://apps.splunk.com/app/1603/ where you can see how it is done using a sparkline, but this will work on a chart as well.

<table>
      <title>Basic Sparkline w/ Max Value Indicator</title>
      <searchString>index=_internal | chart count sparkline by sourcetype | sort -count</searchString>
      <earliestTime>-24h@h</earliestTime>
      <latestTime>now</latestTime>
      <option name="wrap">true</option>
      <option name="rowNumbers">true</option>
      <option name="dataOverlayMode">none</option>
      <option name="drilldown">cell</option>
      <option name="count">5</option>

      <!-- Set sparkline options here; make sure that field matches field name of the search results -->      
      <format type="sparkline" field="sparkline">
        <option name="lineColor">#5379af</option>
        <option name="fillColor">#CCDDFF</option>
        <option name="lineWidth">1</option>
        <option name="maxSpotColor">#A2FFA2</option>
        <option name="spotRadius">3</option>
        <option name="height">25px</option>
      </format>
