ChartSeries<T, D> class abstract

This class holds the property of series.

Chart series has property to render the series if the property data source is empty it renders an empty chart. ChartSeries is the base class, it has the property to set the name, data source, border color and width to customize the series.

Provides options that are extended by the other sub classes such as name, point color mapper, data label mapper, animation duration and border-width and color for customize the appearance of the chart.

Properties

animationDelay → double
Delay duration of the series animation.It takes a millisecond value as input. By default, the series will get animated for the specified duration. If animationDelay is specified, then the series will begin to animate after the specified duration.
final
animationDuration → double
Duration of the series animation. It takes millisecond value as input.
final
borderWidth → double
Border width of the series.
final
color → Color?
Color of the series.
final
dataLabelMapper → ChartValueMapper<T, String>?
Field in the data source, which is considered as text for the data points.
final
dataLabelSettings → DataLabelSettings
Customizes the data labels in a series. Data label is a text, which displays the details about the data point.
final
dataSource → List<T>?
Data required for rendering the series. If no data source is specified, empty chart will be rendered without series.
final
emptyPointSettings → EmptyPointSettings
Customizes the empty points, i.e. null data points in a series.
final
enableTooltip → bool
Enables or disables the tooltip for this series. Tooltip will display more details about data points when tapping the data point region.
final
hashCode → int
The hash code for this object.
no setterinherited
initialIsVisible → bool
Visibility of the series.
final
initialSelectedDataIndexes → List<int>?
List of data indexes to initially be selected.
final
isVisibleInLegend → bool
Toggles the visibility of the legend item of this specific series in the legend.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
legendIconType → LegendIconType
Shape of the legend icon. Any shape in the LegendIconType can be applied to this property. By default, icon will be rendered based on the type of the series.
final
legendItemText → String?
Text to be displayed in legend. By default, the series name will be displayed in the legend. You can change this by setting values to this property.
final
markerSettings → MarkerSettings
Indication of data points.
final
name → String?
Name of the series. The name will be displayed in legend item by default. If name is not specified for the series, then the current series index with ‘series’ text prefix will be considered as series name.
final
onPointDoubleTap → ChartPointInteractionCallback?
Called when double tapped on the chart data point.
final
onPointLongPress → ChartPointInteractionCallback?
Called when long pressed on the chart data point.
final
onPointTap → ChartPointInteractionCallback?
Called when tapped on the chart data point.
final
opacity → double
Opacity of the series. The value ranges from 0 to 1.
final
pointColorMapper → ChartValueMapper<T, Color>?
Field in the data source, which is considered as fill color for the data points.
final
positions → List<ChartDataPointType>
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
selectionBehavior → SelectionBehavior?
Customizes the data points or series on selection.
final
slots → Iterable<SeriesSlot>
Returns a list of all available slots.
no setteroverride
sortFieldValueMapper → ChartValueMapper<T, dynamic>?
Field in the data source, which is considered for sorting the data points.
final
sortingOrder → SortingOrder
The data points in the series can be sorted in ascending or descending order. The data points will be rendered in the specified order if it is set to none.
final
xValueMapper → ChartValueMapper<T, D>?
Field in the data source, which is considered as x-value.
final

Methods

childForSlot(SeriesSlot slot) → Widget?
Returns the widget that is currently occupying the provided slot.
override
createElement() → SlottedRenderObjectElement<SeriesSlot, RenderObject>
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
createRenderer() → ChartSeriesRenderer<T, D>
createRenderObject(BuildContext context) → ChartSeriesRenderer<T, D>
Creates an instance of the RenderObject class that this RenderObjectWidget represents, using the configuration described by this RenderObjectWidget.
override
debugDescribeChildren() → List<DiagnosticsNode>
