Various bug fixes

[anderspeders]

generally breakdown by commodity pie chart

fix time buttons (they work but they don’t change colour when you click on them) or replace with a slider? add companies for that particular year and total revenue, plus possibly breakdown by commodity for

each company if that wouldn’t be too confusing for the UI

add legend

line charts add legend add pop-up for data point (to tell you exact amount at that data point)
