Creates and draws a polar stereographic map.
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl" load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl" function gsn_csm_map_polar ( wks  : graphic, res  : logical ) return_val  : graphic
A variable containing an optional list of plot resources, attached as attributes. Set to True if you want the attached attributes to be applied, and False if you either don't have any resources to set, or you don't want the resources applied.
A scalar id of the map plot created is returned. This is useful if you want to use setvalues to change some plot options after this function has been called.
This function creates and draws a polar stereographic map plot on the given workstation. The default is to show only the northern hemisphere, unless the special resource gsnPolar is set to "SH".
This function puts special longitude labels around the polar map. These labels can be controlled only through a limited set of gsnPolar* resources. To turn off the labels completely, set the resource gsnTickMarksOn to False.
For the map, the following will happen automatically:
- the continents will be colored gray
- the continental outlines will be turned off
- the longitude locations will be labeled
To maximize the area that the plot is drawn in, set the special resource gsnMaximize to True.
