CategoryHighlightLayer Class

Represents an annotation layer that targets a category axis, or all category axes in the chart. If the axis contains any series that are aligned between major gridlines of the axis (column, waterfall, etc) this will render a shape that fills the current category. Otherwise it will render a band with an adjustable thickness at the closest gridline to the pointer position. Setting UseIterpolation to true will cause the x position in the latter case to become affixed to the x position of the pointer.
