Hi @niketnilay - My series is not fixed. And I just want to make the bigger pie slices bold.

Any working use-case with similar requirement? Somehow couldn't attach the image to the reply to your comment. So, posting it as an answer.

@Nadhiya, you can try out Simple XML CSS Extension. Provided your pie chart has id="pieChartWithCSS". Following CSS Selector can be used:

       #pieChartWithCSS .highcharts-data-label text tspan{
         font-size:200% !important;
       }

alt text

Following is the Simple XML code for run anywhere dashboard:

<dashboard>
  <label>Pie Chart Label Font Size</label>
  <row>
    <panel>
      <chart>
        <title>Regular Pie Chart Label</title>

          <sampleRatio>1</sampleRatio>

@niketnilay This solution resulted in Overlapping the label text with the single line coming out of the Pie chart. This happens when you have more than one pie chart in a row. Also, I have seen that the increased text gets overlapped with the pie chart slices.
I think this solution is feasible only when you have single pie chart in a row.

@niketnilay - Is there a way to make the font of "ERROR" alone bold using CSS?

I have a trellis pie chart and am looking to bold the pies (of each trelli) with maximum count (bigger pie slice)

Thanks
Naresh

@nareshinsvu if you ensure that the series labels are always present then you can apply this kind of format using CSS alone. For example in above scenario ERROR will always be series0 (if ERROR is not there its value should be 0) and WARN is series1 due to alphabetical order. You can refer to one such example on Splunk Answers: https://answers.splunk.com/answers/615999/pie-chart-vs-label-colors.html

If series is not fixed i.e. sometimes ERROR will not be there at all then you would need jQuery and SplunkJS for the override as that would be dependent on render of Pie Chart whether ERROR exists or not.
