WOILineGraph class

WOILineGraph is a simple and easy to use line graph widget.

Here is an example of the WOILineGraph

 WOILineGraph(
            height: 300,
         width: 340,
      yaxisValues: const [0.1, 0.2, 0.3, 0.4, 10, 0.6, 0.7, 0.8, 0.1],
   xaxisValues: const [1, 2, 3, 4, 5, 6, 'Sun', '', ''],
filledGraph: true,
   dottedYaxis: true,
  dataPointColor: Colors.grey,
dataPointSize: 2,
xaxisAndTextGap: 20,
 xaxisSeparatorLength: 3,
fillColor: Colors.lightBlue.withOpacity(0.2),
lineColor: Colors.blue,
),

Constructors

WOILineGraph({Key? key, required double height, required double width, required List<LineProperties> yaxisValues, required List xaxisValues, double yaxisTextBoxWidth = 40, Color backgroundColor = Colors.white, double xaxisSeparatorLength = 3, double xaxisAndTextGap = 30, double topSpacing = 10, double bottomSpacing = 0, double leftSpacing = 0, Color incrementLineColor = Colors.red, bool dottedYaxis = false, Text? heading, Text? xaxisLabel, Text? yaxisLabel})
The WOILineGraph essentially requires four variables i.e height, width, xaxisValues, yaxisValues. Number of entries should be equal in the xaxisValues and the yaxisValues list.

Properties

backgroundColor → Color
Background color of the graph
final
bottomSpacing → double
Adds spacing to the bottom. Will need to be adjusted when adding an xaxis label.
final
dottedYaxis → bool
Change the style of the yaxis lines from solid to dotted.
final
hashCode → int
The hash code for this object.
no setterinherited
heading → Text?
Heading text to indicate what the graph represents
final
height → double
The height from the xaxis to the top most increment.
final
incrementLineColor → Color
Color of the yaxis increment lines. Set this to transparent to get rid of the lines.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
leftSpacing → double
Adds spacing to the left. Will need to be adjusted when adding an yaxis label.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
topSpacing → double
Changes height of the widget to adjust for how much of the top area needs to be incorporated in the background color. Will also be needed when adding heading.
final
width → double
The width of the complete widget.
final
xaxisAndTextGap → double
Gap between the xaxis and its values.
final
xaxisLabel → Text?
Label text to indicate what the xaxis reporesents
final
xaxisSeparatorLength → double
Length of the vertical lines separating each xaxis increment.
final
xaxisValues → List
The xaxis points for every data point.
final
yaxisLabel → Text?
Label text to indicate what the xaxis reporesents
final
yaxisTextBoxWidth → double
Width of the text box wrapping the increments on the yaxis. This can be used to fix overflow issues if the text size increases.
final
yaxisValues → List<LineProperties>
The yaxis points for every data point.
final

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<WOILineGraph>
Creates the mutable state for this widget at a given location in the tree.
override
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
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
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → 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.
