void plot(dynamic series, dynamic data) {
  //Ensure the databinding is not null, empty, or the string null
 if (x == null || x == "" || x?.toLowerCase() == "null" || y == null || y == "" || y?.toLowerCase() == "null"){
   return;
 }
 else {
   labels.add(label ?? "");
    FlSpotExtended point =
    FlSpotExtended(series, data, toDouble(x) ?? 0, toDouble(y) ?? 0);
    lineDataPoint.add(point);
  }
