copyWith method
Lets a policy delegate to another with a substituted extent — see
VisibleAxisRange, which narrows dataScalarRange to the visible
window and hands the result to AutoAxisRange.
Implementation
AxisRangeContext copyWith({ScalarRange? dataScalarRange}) {
return AxisRangeContext(
dataScalarRange: dataScalarRange ?? this.dataScalarRange,
scale: scale,
visibleX: visibleX,
extentIn: extentIn,
);
}
