NhlRemoveOverlay

This function is used to remove one or more plots from an overlay. (See NhlRemoveOverlay.)

Synopsis

	function NhlRemoveOverlay( 
		base[1]:graphic,
		plot[*]:graphic,
		restore[1]:logical
	)

Arguments

base: References the HLU plot that is the base of an overlay.
plot: An array of one or more HLU plots to be removed from the base.

restore

Single-dimensioned logical value. If True and the member plot initially was a base plot of an overlay with its own members, the member plots are returned to the plot being removed.

Description

This function removes all of the elements of the plot array from the base plot and applies the restore value to each element. The restore parameter dictates how overlay elements that are themselves overlay bases handle their members. (See the HLU PlotManager description for more detail about overlays.)
