Reply To: Pie chart empty if value 0

[Manoj Mohan]

@kpandey017,

It is not possible to show pie slices when all the dataPoints has 0 value as of now. However, you can achieve similar functionality by changing chart type to doughnut, pushing one extra dataPoint with non-zero y-value and setting innerRadius to 99% as shown in the code snippet below

function checkForZeroDps(chart) {
  var isDpsZero = false;
  for(var i = 0; i < chart.options.data[0].dataPoints.length; i++) {
    if(chart.options.data[0].dataPoints[i].y === 0) {
      isDpsZero = true;
    }
  }
  if(isDpsZero) {
    chart.options.data[0].type = "doughnut";
    chart.options.data[0].innerRadius = "99%";
    chart.options.data[0].dataPoints.push({
      y: 0.000001,
      indexLabel: " ",
      indexLabelLineThickness: 0,
      toolTipContent: null
    });
  }
}

Please take a look at this JSFiddle for complete code.
