LineChartData class

LineChart needs this class to render itself.

It holds data needed to draw a line chart, including bar lines, spots, colors, touches, ...

Constructors

LineChartData({List<LineChartBarData> lineBarsData = const [], List<BetweenBarsData> betweenBarsData = const [], FlTitlesData titlesData = const FlTitlesData(), ExtraLinesData? extraLinesData = const ExtraLinesData(), LineTouchData lineTouchData = const LineTouchData(), List<ShowingTooltipIndicators> showingTooltipIndicators = const [], FlGridData? gridData = const FlGridData(), FlBorderData? borderData, RangeAnnotations? rangeAnnotations = const RangeAnnotations(), double? minX, double? maxX, double? baselineX, double? minY, double? maxY, double? baselineY, FlClipData? clipData = const FlClipData.none(), Color? backgroundColor})
LineChart draws some lines in various shapes and overlaps them. lines are defined in lineBarsData, sometimes you need to fill space between two bars with a color or gradient, you can use betweenBarsData to achieve that.

Properties

backgroundColor ↔ Color
A background color which is drawn behind the chart.

borderData ↔ FlBorderData
Holds data to drawing border around the chart.
getter/setter pairinherited
clipData ↔ FlClipData
clip the chart to the border (prevent draw outside the border)

runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
showingTooltipIndicators → List<ShowingTooltipIndicators>
You can show some tooltipIndicators (a popup with an information) on top of each LineChartBarData.spots using showingTooltipIndicators, just put line indicator number and spots indices you want to show it on top of them.
final

If set to true, the toString method will be overridden to output this instance's props.

Copies current LineChartData to a new LineChartData, and replaces provided values.
lerp(BaseChartData a, BaseChartData b, double t) → LineChartData
Lerps a BaseChartData based on t value, check Tween.lerp.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
