How to view a saved matplotlib plot

Question

I have successfully saved my graphs using the plt.savefig() function in the matplotlib library.

When I try to open my graph using vi, the file is there but there are a lot of strange characters. I guess I'm viewing the code and other info rather than the visualization of the graph. How do I see the graph in its pictoral form?

Answer 1

Vi is a text editor, and can't view images as images. The Windows Paint program should be able to view them, however, or on a Mac, Preview should work.
