NCAR Graphics is comprised of a library containing over two dozen Fortran/C utilities for drawing contours, maps, vectors, streamlines, weather maps, surfaces, histograms, X/Y plots, and annotations. NCAR is an ANSI/ISO standard version of GKS, with both C and FORTRAN callable entries, as well as a math library containing a collection of C and Fortran interpolators and approximators for one-dimensional, two-dimensional, and three-dimensional data. NCAR includes applications for displaying, editing, and manipulating graphical output map databases and hundreds of FORTRAN and C examples, demo programs, compilation scripts.

To uses NCAR Graphics you must use it with the correct Compilers. by default the compilers on Spirit are: intel-compilers/12.1.0 This set of compilers were used when building the NCAR Graphics version: ncar/5.2.1-intel

To use the ncar/5.2.1-gcc version, you must swap out the default compilers for the GCC compilers.
swap module intel-compilers/12.1.0 gcc-compilers/4.4.6

NOTE: After loading the appropriate version of NCAR based on your loaded compilers, a list of commands and a quick example is printed to the screen.

No license is needed to run NCAR Graphics.
