By help of SPLUNK support I got this to work i simple XML:
(Replace the ( ) with < >)
(option name="charting.axisY")numeric(/option)
(option name="charting.axisY.minimumNumber")96.00(/option)
(option name="charting.axisY.maximumNumber")100.50(/option)
(option name="charting.axisY.includeZero")true(/option)
(option name="charting.axisLabelsY.integerUnits")false(/option)
(option name="charting.axisLabelsY.majorUnit")0.5(/option)
This works in*advanced XML:*
(Replace the ( ) with < >)
These will go under the (module name="HiddenChartFormatter") line in the advanced xml view.
(param name="charting.chart")column(/param)
(!-- Define Min and Max Range of Y axis --)
(param name="charting.axisY")numeric(/param)
(param name="charting.axisY.minimumNumber")96.00(/param)
(param name="charting.axisY.maximumNumber")100.50(/param)
(param name="charting.axisY.includeZero")true(/param)
(!-- Define Unit --)
(param name="charting.axisLabelsY.integerUnits")false(/param)
(param name="charting.axisLabelsY.majorUnit")0.5(/param)
Not possible - ref answer from SPLUNK support:
Unfortunately splunk does not have a module that will allow you to change the chart settings to decimals. I asked another support engineer well experienced with charting and functionality and he stated that this ability does not exist as of right now. It may be something that will be available in a future release.
