ScatterSeries<T, D> class
Renders the scatter series.
To render a scatter chart, create an instance of ScatterSeries, and add it to the series collection property of SfCartesianChart.
The following properties, such as color, opacity, borderWidth, borderColor can be used to customize the appearance of the scatter segment.

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.
finalinherited
- animationDuration → double
-
Duration of the series animation. It takes millisecond value as input.
finalinherited
- borderColor → Color
-
final
- borderGradient → LinearGradient?
-
Fills the border of the chart series with gradient color.
finalinherited
- borderWidth → double
-
Border width of the series.
finalinherited
- color → Color?
-
Color of the series.
finalinherited
-
dashArray
→ List<
double> ? -
Dashes of the series.
finalinherited
-
dataLabelMapper
→ ChartValueMapper<
T, String> ? -
Field in the data source, which is considered as text for the data points.
finalinherited
- dataLabelSettings → DataLabelSettings
-
Customizes the data labels in a series. Data label is a text, which
displays the details about the data point.
finalinherited
-
dataSource
→ List<
T> ? -
Data required for rendering the series. If no data source is specified,
empty chart will be rendered without series.
finalinherited
- emptyPointSettings → EmptyPointSettings
-
Customizes the empty points, i.e. null data points in a series.
finalinherited
- enableTooltip → bool
-
Enables or disables the tooltip for this series. Tooltip will display more
details about data points when tapping the data point region.
finalinherited

List of data indexes to initially be selected.
finalinherited
- isVisibleInLegend → bool
-
Toggles the visibility of the legend item of this specific series
in the legend.
finalinherited
- 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.
finalinherited
- 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.
finalinherited
- markerSettings → MarkerSettings
-
Indication of data points.
finalinherited
- 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.
finalinherited
-
onCreateRenderer
→ ChartSeriesRendererFactory<
T, D> ? -
Used to create the renderer for custom series.
finalinherited
- onCreateShader → CartesianShaderCallback?
-
Fills the data points with the gradient and image shaders.
finalinherited
- onPointDoubleTap → ChartPointInteractionCallback?
-
Called when double tapped on the chart data point.
finalinherited
- onPointLongPress → ChartPointInteractionCallback?
-
Called when long pressed on the chart data point.
finalinherited
- onPointTap → ChartPointInteractionCallback?
-
Called when tapped on the chart data point.
finalinherited
-
onRendererCreated
→ SeriesRendererCreatedCallback<
T, D> ? -
Triggers when the series renderer is created.
finalinherited
- opacity → double
-
Opacity of the series. The value ranges from 0 to 1.
