ScatterPlotChart class

A scatter plot draws series data as a collection of points in a two dimensional Cartesian space, plotting two variables from each datum at a point represented by (domain, measure).

A third and fourth metric can be represented by configuring the color and radius of each datum.

Scatter plots render grid lines along both the domain and measure axes by default.

Properties

animatingThisDraw → bool
no setterinherited
animationPercent ↔ double
A value in the range [0.0, 1.0] that indicates the animation progress.
getter/setter pairinherited
behaviors → List<ChartBehavior<num>>
Returns a list of behaviors that have been added.
no setterinherited
chartHeight → int?
no setterinherited
chartIsDirty → bool
If the chart configuration has changed and requires a redraw.
no setterinherited
chartWidth → int?
no setterinherited
context ↔ ChartContext
getter/setter pairinherited
currentSeriesList → List<MutableSeries<num>>
no setterinherited
defaultRenderer ↔ SeriesRenderer<num>
getter/setter pairinherited
disjointMeasureAxisSpecs ← LinkedHashMap<String, NumericAxisSpec>?
Sets a map of disjoint measure axes for the chart.
no getterinherited
domainAxis → Axis<num>?
no setterinherited
domainAxisSpec ← AxisSpec<num>
Create a new domain axis and save the new spec to be applied during configurationChanged.
no getterinherited
drawableLayoutAreaBounds → Rectangle<int>
Returns the combined bounds of the chart draw area and all layout components that draw series data.
no setterinherited
drawAreaBounds → Rectangle<int>
Returns the bounds of the chart draw area.
no setterinherited
flipVerticalAxisOutput ↔ bool
If set to true, the vertical axis will render the opposite of the default direction.
getter/setter pairinherited
gestureProxy → ProxyGestureListener
no setterinherited
graphicsFactory ↔ GraphicsFactory?
Internal use only.
getter/setter pairinherited
hashCode → int
The hash code for this object.
no setterinherited
isTappable → bool
Whether or not the chart will respond to tap events.
no setterinherited
marginBottom → int
no setterinherited
marginLeft → int
no setterinherited
marginRight → int
no setterinherited
marginTop → int
no setterinherited
primaryMeasureAxisSpec ← NumericAxisSpec?
Sets the primary measure axis for the chart, rendered on the start side of the domain axis.
no getterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
secondaryMeasureAxisSpec ← NumericAxisSpec?
Sets the secondary measure axis for the chart, rendered on the end side of the domain axis.
no getterinherited
selectExactEventLocation → bool
Whether selected data should be restricted to only have points that cover this event location.
no setterinherited
selectNearestByDomain → bool
Select data by relative Cartesian distance. Scatter plots draw potentially overlapping data in an arbitrary (x, y) space, and do not consider the domain axis to be more or less important for data selection than the measure axis.
no setteroverride
selectOverlappingPoints → bool
On scatter plots, overlapping points that contain the click/tap location are all added to the selection.
no setteroverride
transition ↔ Duration
getter/setter pairinherited
vertical ↔ bool
