Poor Graphic
Drawbacks
- Changing scale of the time line in mid-axis to make exponential growth linear (from slides). This is called the Lie Factor
- The Lie Factor also makes one believe that there's continuity in the data.
- Bad Data-Ink-Ratio
- It is not very aestetic
- Could have some more colors
- Quite a lot of Chart Junk can be found in the graphic. The pictures of the doctors and the pictures of the other working men for example.
- 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 working men.
Improvements
- Choose linear time scale without jumps
- Analyze distribution (linear, exponential?)
- Choose appropriate diagram type
- Make the design simpler, without making it less understandable.
- Make a scale on the left side.
- 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 working men),
- Grouped the legend into a single block
