Implementation

@override

  final Map<String, dynamic> json = <String, dynamic>{};
  if (background != null) {
    json['background'] = background!.toJson();
  }
  if (height != null) {

  }
  if (line != null) {

  }
  if (point != null) {
    json['point'] = hcJsonValue(point);
  }
  if (points != null) {
    json['points'] = points!.map((e) => hcJsonValue(e)).toList();
  }

  }
  if (xAxis != null) {
    json['xAxis'] = xAxis;
  }
  if (yAxis != null) {
