Please read Chapter 1 first and follow the instructions there regarding the setting of various environment variables before running Python and PyGraph. Then, once you have fired up python, you need to execute import statements for each component of the OOG which you intend to use. There are two forms of the import statement.
(xxxx is the name of the file imported, but without the ``.py'' suffix.) This form imports the name space from file xxxx into the name space where the import statement is executed. Thus, if foo is a name in xxxx's name space, then it may be referred to simply as foo.
This form imports only the name xxxx, so that if foo is a variable in the xxxx name space, then it must be referred to as xxxx.foo.
Following is a list of the OOG files available in PyGraph, and the names of the classes (capitalized) and functions (lower case) which are declared in the files which you may want to use:
Note that if you want to instantiate both a PyNarcisse and a PyGist Plotter, you must use the ``import xxxx'' form of the import statement.
