Do not display value when equal to 0 flexmonster

Hello,
 
Thank you for posting on our forum.
 
We suggest using the customizeChartElement hook to implement the desired behavior.
For your case, the handler would look similar to the following:

function customizeChartElementFunction(element, data) {
  if (data.type === "series_label" && data.value === 0) {
    element.remove();
  }
}

 
We have also prepared the JSFiddle for your reference: https://jsfiddle.net/flexmonster/57ytzjmu/.
 
Please let us know if it works well for you.
Looking forward to hearing your feedback.
 
Kind regards, Illia
