Document Summary
Important baselines: average trem lines, bubble charts, circles should be avoided for comparisons. But charts and graphs also differ: avoid making the title or legend a general topic, do not give background information or characterize what the data imply, be sure labels distinguish graphics presenting similar data. Insert into the table or figure information that helps readers see how the data support your point.
