pub fn labels_alignment(self, alignment: Alignment) -> Axis<'a>

Defines the alignment of the labels of the axis. The alignment behaves differently based on the axis:

  • Y-Axis: The labels are aligned within the area on the left of the axis
  • X-Axis: The first X-axis label is aligned relative to the Y-axis
