To do

  • tooltips (scroll over time and price)
  • plot trades
  • add in initial interest
    • initial nonzero interest
    • initial zero interest
  • y axis ticks: show every 2^n, depends on zoom level
  • max pan
  • max/min zoom
  • move viz to blog
  • best bid best ask lines
  • last trade line
    • tried it out, makes viz too cluttered
  • cumulative interest plot
  • brush zoom
  • remaining colors
    • most colors too light: what is the distribution of remaining values?
    • use usual color scheme (Dark2)
