Poor Graphic

Incomes of Doctors Vs. Other Professionals

Problems:

• 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.

Proposals for new graphic:

• 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.

Good Graphic
