Comparing Chaffetz's propaganda graph and a true representation based on actual numbers

This refers to earlier posts today about the Tuesday congressional hearing on Planned Parenthood, where committee chair Jason Chaffetz sprang the first graph on PP CEO Cecile Richards, and she slayed his argument by pointing out the small print at the bottom giving the source as American United for Life, an anti-abortion group.   The problem with the graph is that the two lines are completely out of scale with each other;   the graph has no common Y-axis.   It's just a made-up picture of one thing going up and another going down -- deliberately distorted to make it seem that abortions have shot up, while cancer screenings have sharply declined.
 
The lower graph uses the same numbers and constructs a graph as it should be to show proportionality:   see how both lines are plotted to the same numbers on the vertical or Y axis.   Here the slight increase in abortions hardly seems significant.   While there is a much greater decline in cancer screenings, the Note in the middle of the graph explains that as due to major changes in the American Cancer Society's recommended frequency of various cancer screenings during the period.


There is no way to read this other than the intended grand "gotcha" moment of the hearings.   It failed completely and left Chairman Chaffetz looking not only indecently partisan but inept as well.
