All example code assumes the following imports have been made, where numpy is usually not required but it is for some of the examples:

Example Datasets

The examples make use of a small number of sample datasets. These are available to view and download from a dedicated directory in the codebase repository. Alternatively, they may be downloaded together as a pair of zip files (split into two parts to fit within GitHub file size limits, total size ~125 MB) available from here (part 1 of 2) and here (part 2 of 2) which can be unzipped together to the full dataset directory as follows:

Accessing all of the datasets for the cf-plot examples
