DefaultIterativeLabelLayoutStrategy class
Strategy of achieving that labels do not overlap ("fit") on an axis.
Currently only used on the X axis, this strategy defines a sequence of steps, each performing a specific strategy to achieve labels fit.
When the layout
finds labels overlap, the following steps are taken
to achieve "fit" of labels: LabelFitMethod.rotateLabels,
LabelFitMethod.decreaseLabelFont and LabelFitMethod.skipLabels.
The steps are repeated at most maxLabelReLayouts
times.
If a "fit" is not achieved on last step, the last step is repeated
until maxLabelReLayouts
is reached.

Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- isRotateLabelsReLayout → bool
-
Should return true if the layout strategy rotates labels during the
current reLayout.
This is needed by paint methods to rotate canvas.
no setteroverride
- labelFontSize → double
-
no setteroverride
- labelTiltMatrix → Matrix2
-
Rotation matrix corresponding to the angle by which labels are tilted.
no setteroverride
- labelTiltRadians → double
-
In addition to the rotation matrices, hold on radians for canvas rotation.
no setteroverride
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- showEveryNthLabel → int
-
Always showing first label, and after, label on every nth dimension point.
Allows to "thin" labels to fit.
