Overview of the PyNGL examplesThe PyNGL examples give you an overview of the graphic capabilities of the package and provide a tutorial introduction. Other useful example-related links are provided - a summary is presented in a list below.
Many examples require the Nio module from PyNIO to read in NetCDF, GRIB, HDF, shapefile, and other self-documenting formats.
The general code structure of the PyNGL examples is as follows:
- Read data
- Data are either generated from within the PyNGL script or read from
either an ASCII file or a netCDF file.
- Process data
- Some of the examples show how to process data by converting units,
masking values, interpolating to a regular grid, and so forth.
- Visualize data
- Almost every example generates one or more visualizations, including
XY plots, contour plots, vector plots, map plots, and streamline plots.
- Write data
- Some of the examples show how to write data to a file.
Useful example-related links.
- Provides all graphic images produced from PyNGL examples as well as links to all source codes used to create the examples.
- An alphabetical listing of all PyNGL examples together with brief descriptions and links to the sources.
- A step-by-step guide to PyNGL that introduces new concepts through a series of example Python scripts. Each of the eleven examples contains line-by-line descriptions.
- by category
- Lists the examples by category (such as "contouring", "vectors", and so forth) and provides links to the examples in those categories.
- by function
- For any given PyNGL function, this page lists all the examples where that function is called.
- by resource
- For any given PyNGL resource that is used in an example, this page lists all the example where the resource is used.
