  2. Here is a graph... Company Earnings

  3. Easy to Understand, but... Company Earnings not very impressive......

  4. Company Earnings

  5. That’s better.... Company Earnings In this “Truncated Graph”, the line climbs halfway up the graph. But why stop there?......

  6. Company Earnings

  7. Company Earnings

  8. Now THAT’S Company Earnings a PROFIT!

  9. Same Data....... very different graphs.

  10. It all depends... on what you want to say...

  11. Here is a simple honest graph.... Average Worker’s Salary Dollars per day Showing that American workers earn twice as much as Rotundians

  12. Average Worker’s Salary Dollars per day but it lacks EYE-APPEAL...

  13. Average Worker’s Salary How about a pretty PICTOGRAPH? Twice as many moneybags means twice as much money earned...

  14. Average Worker’s Salary But I want to create a stronger impression of how much better-off the American worker is...

  15. So I draw the Rotundian’s moneybag... Average Worker’s Salary

  16. Average Worker’s Salary and then I draw the American worker’s moneybag TWICE as TALL

  17. ..so the American’s salary Average Worker’s Salary appears to dwarf the Rotundian’s! (...that’s not being dishonest, is it?)

  18. Here is a simple graph showing changes in a frog population Number of Frogs

  19. Here is the same data presented in a pictograph...

  20. ...and another pictograph... How might this graph create an incorrect impression?

  21. How to Lie with G raphs

  22. Use Truncated Graphs (graphs that don’t start at zero) Use Stretched Graphs or Scrunched Graphs Use Pictographs (w/ objects that get wider and taller) ...just don’t get caught...
