Hi Adam,
Thank you for your comments. It's my opinion that abuse of charts goes in both directions. Many analysts produce charts that purport to demonstrate a compelling picture, and with very little other data used to support some sort of trade recommendation or intellectual point. Yet, on the other side, analysts being asked to evaluate a trade or point frequently do not insist on more information beyond the image and the opinions of the analyst. A poor state of affairs.
Thank you also for reminding folks that r-squared is only useful if the conditions for normality are present.
With smiles!
Jason
