All "cbook.get_sample_data(..., asfileobj=False)" does is returns the full filename path to a given file stored in our package for demonstration purposes. You can ignore that entirely. Just say "fname = 'foobar.csv'" and have your own csv file called "foobar.csv" sitting in your current working directory. "plotfile()" works by reading in a CSV file and plotting the columns given. So, the CSV file will need in its first line those column headers. The first one given will be for the x-axis, while the rest are for the individual lines.
