BarPoint class

One bar. Stored as a ChartPoint whose y is toY, so trackball snapping, gap handling, and x/y extent tracking work unchanged.

Inheritance

Constructors

BarPoint(double x, double toY, {double fromY = 0, BarStyle? style, List<BarStackSegment> stack = const [], BarBackground? background})
const
BarPoint.dateTime(DateTime x, double toY, {double fromY = 0, BarStyle? style, List<BarStackSegment> stack = const [], BarBackground? background})
BarPoint.gap(double x)
No bar at this x (keeps slots addressable for grouped charts).
const

Properties

background → BarBackground?
Passive bar painted behind this one; widens yExtent so the track is always fully in range.
final
fromY → double
The bar's base (default 0).
final
hashCode → int
The hash code for this object.
no setteroverride
isGap → bool
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stack → List<BarStackSegment>
Colored slices of a stacked bar; empty for a plain bar.
final
style → BarStyle?
Per-datum override of the series-level BarStyle, merged field-by-field.
final
toY → double
The bar's top; identical to y. Non-null by construction except for BarPoint.gap.
no setter
x → double
Position along the x axis, in that axis's domain values — epoch milliseconds for a DateTimeAxis.
finalinherited
xAsDateTime → DateTime
no setterinherited
y → double?
Value along the y axis, or null for a gap.
finalinherited
yExtent → (double, double)?
The y span this datum occupies, for axis auto-ranging; null = gap. A plain point occupies (y, y); range-like subclasses (e.g. bars) override.
no setteroverride
