ChartAreaContainer class abstract
Base class which manages, lays out, moves, and paints each top level block on the chart. The basic top level chart blocks are:
- ChartTopContainer - the whole chart
- LegendContainer - manages the legend
- YContainer - manages the Y labels layout, which defines:
- Y axis label sizes
- Y positions of Y axis labels, defined as yTickY. yTicksY s are the Y points of scaled data values and also Y points on which the Y labels are centered.
- XContainer - Equivalent to YContainer, but manages X direction layout and labels.
- DataContainer and extensions - manages the area which displays:
- Data as bar chart, line chart, or other chart type.
- Grid (this includes the X and Y axis).
See Container
for discussion of roles of this class.
This extension of Container
has the added ability
to access the container's parent, which is handled by
chartTopContainer.
Constructors
- ChartAreaContainer({required ChartTopContainer chartTopContainer})
Properties
- chartTopContainer → ChartTopContainer
-
The chart top level.
final
- enableSkipOnDistressedSize ↔ bool
-
If size constraints imposed by parent are too tight,
some internal calculations of sizes may lead to negative values,
making painting of this container not possible.
getter/setter pairinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- isDistressed ↔ bool
-
getter/setter pairinherited
- layoutSize ↔ Size
-
Manages the layout size during the layout process in layout.
Should be only mentioned in this class, not super
getter/setter pairinherited
- offset ↔ Offset
-
Current absolute offset, set by parent (and it's parent etc, to root).
getter/setter pairinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- skipByParent ↔ bool
-
skipByParent instructs the parent container that this container should not be
painted or layed out - as if it collapsed to zero size.
getter/setter pairinherited
- tiltMatrix → Matrix2
-
Provides access to tiltMatrix for extension's paint methods.
no setterinherited
Methods
-
applyParentOffset(
Offset offset) → void -
Allow a parent container to move this Container
after layout.
inherited
-
applyParentTiltMatrix(
Matrix2 tiltMatrix) → void -
Tilt may apply to the whole container.
todo-2 unused? move to base class? similar to offset?
