compare bar chart code with line chart code

[acell]

• the bar chart works, but the line chart code doesn't currently work after some changes have been made to the SOCRAT website
• we want to get these deprecated charts up again! code for the line chart (doesn't currently work) and the bar chart (does currently work) are stored similarly -- so go through trying to find the differences
• specifically look at the directives + controllers
• go around changing the line chart code to try to make it work, like the bar chart does
• if you have any questions or need any direction, feel free to message me on slack!
