ConfigSeries

seriesColor

Type	default
Color	null

set single color for entire series

seriesColor: Colors.deepPurple,

customColor

Type	default
Color Function(G group, D data, int? index)?	null

unlike seriesColor, this property allows for dynamic color assignments based on data points

customColor: (group, data, index) {
  return switch (data.domain) {
    'Mon' => Colors.blue,
    'Tue' => Colors.green,
    _ => Colors.deepPurple,
  };
},

areaColor

Type	default
Color Function(G group, D data, int? index)?	null

returns the area color for a given data value. Specify for Line type. Can custom for each group. includeArea must be set to true.

seriesColor: Colors.red,
stacked: true,
includeArea: true,
areaColor: (group, data, index) {
  return switch (group.id) {
    'id' => Colors.green.shade100,
    'id2' => Colors.blue.shade100,
    _ => Colors.purple.shade100,
  };
},

fillColor

Type	default
Color? Function(G group, D data, int? index)?	null

set fill chart where has fill box like bar

fillColor: (group, data, index) {
  return switch (data.domain) {
    'Tue' => Colors.green,
    _ => Colors.deepPurple,
  };
},

fillGradient

Type	default
Gradient? Function(G group, D data, int? index)?	null

If render type is bar, you must set fillPattern to FillPattern.gradient.

fillGradient: (group, data, index) {
  return const LinearGradient(
    begin: Alignment.topCenter,
    end: Alignment.bottomCenter,
    colors: [
      Colors.blue,
      Colors.purple,
    ],
  );
},

strokeGradient

Type	default
Gradient? Function(G group, D data, int? index)?	null

Set gradient color for stroke.

strokeGradient: (group, data, index) => const LinearGradient(
  colors: [Colors.blue, Colors.purpleAccent],
),

targetLineGradient

Type	default
Gradient? Function(G group, D data, int? index)?	null

just like strokeGradient, but better for clip bound size for gradient on each element

targetLineGradient: (group, data, index) {
  return const LinearGradient(
    colors: [Colors.yellow, Colors.cyan],
  );
},

areaGradient

Type	default
Gradient? Function(G group, D data, int? index)?	null

Set gradient for area in line chart. includeArea property must be set to true. and you can adjust alpha channel or opacity from areaOpacity property.

areaGradient: (group, data, index) {
  return const LinearGradient(
    colors: [Colors.red, Colors.amber],
  );
},

fillPattern

Type	default
FillPattern Function(G group, D data, int? index)?	null

dashPattern

Type	default
List<int>? Function(G group, D data, int? index)?	null

specify for line pattern

labelAccessor

Type	default
String Function(G group, D data, int? index)?	null

set custom format value for label series, work for bar type

configSeriesBar: ConfigSeriesBarO(
  showBarLabel: true,
  labelAccessor: (group, data, index) {
    return '${data.measure} km';
  },
),

configSeriesPie: ConfigSeriesPieO(
  showLabel: true,
  arcLabelDecorator: const ArcLabelDecoratorO(
    labelPosition: ArcLabelPosition.outside,
  ),
  labelAccessor: (group, data, index) {
    return '${data.domain}\n${data.measure} km';
  },
),

strokeWidthPx

Type	default
num? Function(G group, D data, int? index)?	null

allows for dynamic stroke width assignments based on data points

strokeWidthPx: (group, data, index) {
  return switch (data.domain) {
    'Mon' => 8,
    _ => 2,
  };
},

radiusPx

Type	default
num Function(G group, D data, int? index)?	null

allows for dynamic radius series assignments based on data points

radiusPx: (group, data, index) {
  return switch (data.domain) {
    'Mon' => 12,
    'Tue' => 3,
    'Wed' => 8,
    _ => 5,
  };
},

measureOffset

Type	default
num Function(G group, D data, int? index)?	null

starting plot measure to draw chart

measure: (group, data, index) {
  return switch (data.domain) {
    'Tue' => data.measure - 70,
    _ => data.measure,
  };
},
measureOffset: (group, data, index) {
  return switch (data.domain) {
    'Tue' => 70,
    _ => 0,
  };
},

domain

Type	default
