Poor Graphic

Incomes of Doctors Vs. Other Professionals

Drawbacks

  • Lie Factor: non-linear time scale shows a linear growth of the salary, but it's exponential,
  • Bad Data-Ink-Ratio: a lot of ink is used to differ the bars and for
  • Chart Junk: pictures of the doctors and other professionals, year is always written with 4-digits.

Improvements

  • Used a linear time scale to show the exponential growth,
  • Additional usage of a line chart to better visualize the higher growth of doctors salary,
  • Removed the chart junk (pictures of doctors and other professionals, and 4-digit years) which results in a better data-ink-ratio,
  • Grouped the legend into a single block,
  • Added a y-axis scale on both sides, because of the high width of the new graphic.
