BarChartRodData class
Holds data about rendering each rod (or bar) in the BarChartWidget.
Constructors
-
BarChartRodData({double? fromY, required double toY, Color? color, Gradient? gradient, double? width, BorderRadius? borderRadius, BorderSide? borderSide, BackgroundBarChartRodData? backDrawRodData, List<
BarChartRodStackItem> ? rodStackItems}) -
BarChartWidget renders rods vertically from zero to
toY, and the x is equivalent to the BarChartGroupData.x value.
Properties
- backDrawRodData → BackgroundBarChartRodData
-
If you want to have a bar drawn in rear of this rod, use backDrawRodData,
it uses to have a bar with a passive color in rear of the rod,
for example you can use it as the maximum value place holder.
final
- borderRadius → BorderRadius?
-
If you want to have a rounded rod, set this value.
final
- borderSide → BorderSide
-
If you want to have a border for rod, set this value.
final
- color → Color?
-
If provided, this BarChartRodData draws with this color
Otherwise we use gradient to draw the background.
It throws an exception if you provide both color and gradient
final
- fromY → double
-
BarChartWidget renders rods vertically from fromY.
final
- gradient → Gradient?
-
If provided, this BarChartRodData draws with this gradient.
Otherwise we use color to draw the background.
It throws an exception if you provide both color and gradient
final
- hashCode → int
-
The hash code for this object.
no setterinherited
-
props
→ List<
Object?> -
Used for equality check, see
EquatableMixin.no setter -
rodStackItems
→ List<
BarChartRodStackItem> -
If you are a fan of stacked charts (If you don't know what is it, google it),
you can fill up the rodStackItems to have a Stacked Chart.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- stringify → bool?
-
If set to
true, the toString method will be overridden to output this instance's props.no setterinherited - toY → double
-
BarChartWidget renders rods vertically from fromY to toY.
final
- width → double
-
BarChartWidget renders each rods with this value.

copyWith(
{double? fromY, double? toY, Color? color, Gradient? gradient, double? width, BorderRadius? borderRadius, BorderSide? borderSide, BackgroundBarChartRodData? backDrawRodData, List< BarChartRodStackItem> ? rodStackItems}) → BarChartRodData - Copies current BarChartRodData to a new BarChartRodData, and replaces provided values.
-
isUpward(
) → bool - Determines the upward or downward direction
-
