@mnair,

y value in datapoint object only accepts numeric value as of now. We suggest you to replace NaN value with null or 0 as shown in the code snippet below:

for(var i = 0; i < chart.options.data[0].dataPoints.length; i++){
  if(isNaN(chart.options.data[0].dataPoints[i].y)){
    chart.options.data[0].dataPoints[i].y = null;
  }
}
