Plot class

A widget that displays a Plot.

The plot will display the Graph objects specified

This sample shows a simple graph:

{@tool snippet}

Plot(
  graphs: [
    Graph(
      x: [0, 1, 2, 3, 4, 5],
      y: [0, 1, 2, 3, 4, 5],
      crosshairs: [
        Crosshair(
          label: 'Crosshair',
          active: true,
          yPadding: 10,
        )],
    )
],)

{@end-tool}

Navigate around the plot by using a mouse or toch pad. The Plot can be scaled with scrolling/panning a mouse or touchpad. The Plot can be scaled on x-axis only by pressing shift + scroll/panning. The Plot can be scaled on y-axis only by pressing ctrl + scroll/panning.

Constructors

Plot({Key? key, required List<Graph> graphs, Ticks? xTicks, Ticks? yTicks, PlotConstraints? constraints, dynamic onConstraintsChanged(PlotConstraints constraints, PlotConstraints extremes)?, double strokeWidth = 1, double padding = 0, double minimumScale = 0.25, double maximumScale = 50})

Creates a widget that displays a Plot

const

Properties

constraints → PlotConstraints?

Initial Plot constraints. If xTicks or yTicks is logarithmic, it is expected that the constraints are in the log10 space.

final

graphs → List<Graph>

The FlutterPlot graphs to paint.

final

hashCode → int

The hash code for this object.

no setter, inherited

key → Key?

Controls how one widget replaces another widget in the tree.

final, inherited

maximumScale → double

The maximum scale factor possible for scaling the plot.

final

minimumScale → double

The minimum scale factor possible for scaling the plot.

final

onConstraintsChanged → dynamic Function(PlotConstraints constraints, PlotConstraints extremes)?

Function called every time the PlotConstraints changes. To optimize performance, do not use this feature! If xTicks or yTicks is logarithmic, the constraints and extremes are in the log10 space.

final

padding → double

The padding to use around the plot borders

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

strokeWidth → double

The width of the graph lines

final

xTicks → Ticks?

The ticks which will annotate the x-axis.

final

yTicks → Ticks?

The ticks which will annotate the y-axis.

final

Methods

build(BuildContext context) → Widget

Describes the part of the user interface represented by this widget.

override

createElement() → StatelessElement

Creates a StatelessElement to manage this widget's location in the tree.

inherited

debugDescribeChildren() → List<DiagnosticsNode>

Returns a list of DiagnosticsNode objects describing this node's children.

inherited

debugFillProperties(DiagnosticPropertiesBuilder properties) → void

Add additional properties associated with the node.

inherited

isEqualConfigTo(Plot other) → bool

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode

Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.

inherited

toLog(bool xLog, bool yLog) → void

toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String

A string representation of this object.

inherited

toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String

Returns a string representation of this node and its descendants.

inherited

toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String

Returns a one-line detailed description of the object.

inherited

toStringShort() → String

A short, textual description of this widget.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
