Matplotlib plots not displaying in sublimetext

Question

I've recently started using sublimetext 2, however I noticed today that the plt.show() function doesn't seem to work when run within sublimetext.

If for example I create the following script:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
plt.show() 

Running this with IDLE generates a plot, however using sublimetext no output is generated. It just keeps 'thinking' until I end the python.exe process after which [Finished] is output.

Have I misunderstood how sublimetext is meant to be used?

Thanks.

More appropriate way is to just add one line in default Python build system file:

"shell": true

Or make additional Python build system with:

{
    "cmd": ["python", "-u", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python",
    "shell": true
}
