scale method

StackableValuePoint scale({ required double scaledX, required YLabelsCreatorAndPositioner yLabelsCreator, })

Scales this point to the container coordinates (display coordinates).

More explicitly, scales the data-members of this point to the said coordinates.

See class documentation for which members are data-members and which are scaled-members.

Note that the x values are not really scaled, as object does not manage the unscaled x (it manages the corresponding label only). For this reason, the scaledX value must be provided explicitly. The provided scaledX value should be the "within ChartPainter absolute" x coordinate (generally the center of the corresponding x label).

Implementation

// todo-01-morph : Calling this 'scale' is suspect - this does not do any X dimension scaling at all!
//                Analyze the uses of the 'scale' term in the system, probably needs improvement.
StackableValuePoint scale({
  required double scaledX,
  required YLabelsCreatorAndPositioner yLabelsCreator,
}) {
  this.scaledX = scaledX;
  scaledY = yLabelsCreator.scaleY(value: dataY);
  scaledFromY = yLabelsCreator.scaleY(value: fromY);
  scaledToY = yLabelsCreator.scaleY(value: toY);
  // todo-01-morph : Can we remove scaledX, scaledFromY, scaledX, scaledToY and only maintain these offsets???
  scaledFrom = ui.Offset(scaledX, scaledFromY);
  scaledTo = ui.Offset(scaledX, scaledToY);

  return this;
