[ncl-talk] Not getting the original lat-lon label in contour map

[Atul Saini]

*lat=a->latprintVarSummary(lat)*

The above given code in ncl itself results into following detail, which
contain the units and other things-













*Variable: latType: floatTotal Size: 200 bytes            50 valuesNumber
of Dimensions: 1Dimensions and sizes: [lat | 50]Coordinates:
lat: [ 8..20.25]Number Of Attributes: 4  standard_name : latitude
long_name : latitude  units : degrees_north  axis : Y*
