symMinMaxPlt

Calculates the minimum/maximum values for a variable and uses nice_mnmxintvl to calculate the symmetric contour interval.

Prototype

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"  ; This library is automatically loaded
                                                             ; from NCL V6.2.0 onward.
                                                             ; No need for user to explicitly load.

	procedure symMinMaxPlt (
		x          : numeric,  
		ncontours  : integer,  
		outside    : logical,  
		res        : logical   
	)

Arguments

A numeric array of any dimensionality.

An integer scalar value indicating the number of contours desired.

A logical value indicating whether the contour values fall just outside or just inside the calculated min and max values. Set to True if outside, and False otherwise.

The resource variable containing all the plot modifications. For example:

  res = True
  res@tiMainString = "title"

Description

This procedure automatically calculates the minimum and maximum values for a variable and then uses nice_mnmxintvl to calculate the symmetric contour interval and sets the resources for the user. This procedure should be used with white-in-the-middle color tables.

The contour intervals contained within the resource variable res will be modified.
