Mixing NCL with HLUs and LLUs
This module describes how to produce plots with code that uses
NCL and calls HLUs and LLUs.
NCL has three statements for interfacing with the
High Level Utilities library:
As well as the three NCL statements above, NCL has versions of most of
the functions available to the HLUs. See
NCL versions of HLU functions and procedures in the NCL commands module.
create allows you to create an
HLU object and assign vlaues to its resources.
setvalues allows you to modify resources in an
HLU object after it has been created.
getvalues allows you to retrieve the values of
the resource setting in an HLU object.
Almost all of the examples available via the ng4ex command
illustrate accessing HLUs from NCL. Type
for details on ng4ex.
There is no way to access the
Low Level Utilities library from
an NCL program without implementing the desired functions by
extending the NCL function set.
