displayDataPointWhenNoValue: false is ignored when using BezierChartScale.WEEKLY

[yaizudamashii]

Version 1.0.17+1

displayDataPointWhenNoValue is ignored and a dot is shown at y axis value 0. (For May 13th in the example.)

Example code:

List<DataPoint<DateTime>> dataPoints = [
  DataPoint<DateTime>(value: 231.0, xAxis: DateTime(2020, 5, 12, 9, 51, 27)),
  DataPoint<DateTime>(value: 231.0, xAxis: DateTime(2020, 5, 14, 10, 59, 35)),
  DataPoint<DateTime>(value: 231.0, xAxis: DateTime(2020, 5, 15, 8, 59, 0)),
];
return BezierChart(
  fromDate: dataPoints.first.xAxis,
  bezierChartScale: BezierChartScale.WEEKLY,
  toDate: dataPoints.last.xAxis,
  series: [
    BezierLine(
      label: "Num posts",
      data: dataPoints,
    ),
  ],
  config: BezierChartConfig(
      verticalIndicatorStrokeWidth: 3.0,
      verticalIndicatorColor: Colors.white,
      showVerticalIndicator: true,
      verticalIndicatorFixedPosition: false,
      verticalLineFullHeight: true,
      displayYAxis: true,
      displayDataPointWhenNoValue: false,
      backgroundColor: Colors.lightBlueAccent,
      footerHeight: 50.0,
  ),
);
