What is the best way to keep my chocolate vine in check?

I recently purchased a home that was left the yard unattended for over a year. I spent last year seeing what I had as I bought the home in Nov 2015. I have over 45 different flowers and shrubs, so it has been a huge undertaking lol. But I have a chocolate vine that starts on a pole, we cut off about 5 miles off it last yr. I didn't cut it down to the base, should I have done so? What is the best way to prune? Thanks so much!
