This week in chart failure
Real data:
Faux News version of real data (focus on the last data point):
Also, the scale on the left is out of proportion. If you compare the 8.8% point to the 9.1% point, we see there’s two lines of gap, meaning 0.3% = 2 lines, or 0.1% = 0.67 lines. 1% point should be 6.7 lines. Now, compare the gap between 8% and 9% on the y-axis. It’s 3.5 to 4.0 lines!
If we treat the 9% on the y-axis as valid, then where it shows 10%, it should actually be showing about 9.5% or 9.6%.
Glove-slap: Flowing Data.
