Pie Charts | How to style Data Labels

[Altair]

Hi Is there a way of modifying data labels in a pie chart?


I want to have a red glow on the text 2 and 4 or change font size.

You can use CSS to style it:
You will put this on your header.
 

<style>
tspan.highcharts-text-outline {
  stroke: red !important;
}
</style>

You can also try to modify it via JS using HighChart API

Put this on your header:

<script src="https://code.jquery.com/jquery-3.2.1.js"></script>
<script src="https://code.jquery.com/jquery-migrate-3.0.0.js"></script>

Footer:

<script type="text/javascript">
jQuery(window).load(function() {
  Highcharts.charts[0].update({
      series: {

        dataLabels: {
          style: {
            color: "black",
            fontSize: 20,
            textOutline: "none"
          }
        }
      }
    }

  );


});
</script>
