Hey @allspiritseve, I don't actually want this merged, I was just looking for a bit of help. jQuery Sparklines doesn't have a horizontal stacked bar chart; regardless, I put up a normal one that you can see on the instructor dashboard. I put it in the 'team' column since it seemed unused anyway. The other issue I'm having, though, is that when you login, instead of going to the dashboard, it prints the json response. You can still go to the dashboard if you type the URL in.
