Ordinal Bar Chart
const

Properties

allowSliding → bool
give user access to slide chart viewport
set initial viewport in domainAxis
if set true, this will affect to 'measure viewport'. measure viewport will auto adjust depend on min/max from item chart value
To fix this, set viewport in measueAxis
default: false
final
animate → bool
animate chart when build
default: false
final
animationDuration → Duration
duration animate a chart when build
default: Duration(milliseconds: 300)
final
areaColor → AreaColorO?
areaColor returns the area color for a given data value.
If not provided, then group color will be used 10% opacity by default.
Specify for Line type
to activate custom areaColor, ConfigRenderLine -> includeArea must be true
final
barLabelValue → String Function(OrdinalGroup group, OrdinalData data, int? index)?
set custom format value for label bar
final
configRenderBar → ConfigRenderBar
style bar
final
dashPattern → DashPatternO?
set pattern
specify for line pattern
final
domainAxis → DomainAxis?
customize domain axis
final
fillColor → FillColorO?
set fill chart where has fill box like bar
default: based on Group color
final
fillPattern → FillPatternO?
custom fill pattern
default: solid
final
flipVertical → bool?
when vertical is false, you can flip sort domain
top down or bottom up
final
groupList → List<OrdinalGroup>
group
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
layoutMargin → LayoutMargin?
margin from outer chart to wrapper box
default: 20px for each side
final
measureAxis → MeasureAxis?
customize measure axis
final
onChangedListener → void Function(OrdinalData data)?
listen which data is changed selected
final
onUpdatedListener → void Function(OrdinalData data)?
listen which data is selected
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
secondaryMeasureAxis → MeasureAxis?
customize secondary measure axis
final
vertical → bool
set direction length bar to vertical
default: true
final
