The recently released edition of the book, How to Lie with Charts: Investor's Edition, includes the a new Chapter 11: Viewports and Dashboard Displays, which tells how to identify and correct this problem. The price of the new edition has been reduced to $23.99 so it's now the same as the popular second edition, which will eventually be withdrawn from sale. The Kindle price has been reduced to $6.99. Both paperback and ebook versions are available here.
