The Original Wasserman 9 panel Plot, the New Wasserman 9 Panel Plot, the Whipp 9 Panel Plot and the ERS version of the Whipp Plot.
Everybody in the world of cardiopulmonary exercise testing (CPET) is familiar with the 9-Panel Plot. Perhaps the question should be which version. There are certainly four in current use so perhaps it would be of interest to look at them and compare them.
