That is a great Python script for plotting data from multiple text files on the same graph. It is well-written and easy to understand. I especially like the use of the sys.argv variable to get the list of filenames from the command line. This makes the script very flexible and easy to use.

Here is an example of how to use the script:

python plot_data.py data1.txt data2.txt data3.txt
This will plot the data from all three text files on the same graph.
