This is a continuation of this thread: http://jsoftware.com/pipermail/programming/2014-February/035222.html but moved to chat.
I posted a video http://www.youtube.com/watch?v=qXFpgYvbogw with the intent of showing some of J's capabilities. I would be happy to hear any feedback on the video. Looking back at it, I wish I bumped up the font size. It's best viewed full screen. I tried to flip through things pretty quickly to fit in as much as possible. I probably unnecessarily explained things in a few cases. I still need to practice using the right term for the operations too. In terms of my examples, I would like to know if I could put dates somehow on on X-axis. I also worked up an example that used a secondary axis with % change, but I haven't recorded it yet. That might be a continuation. Plotting on a secondary axis is something that J's plot does real easily compared to R.
