Talk:Carpet plot

--MatthiasOberhauser (talk) 19:18, 2 November 2013 (UTC)

I wonder whether raster plots deserve their own article, as they back various things, also including spectrograms Scarfboy (talk) —Preceding undated comment was added at 15:06, 17 December 2008 (UTC).

The subsection on cheater plots could use an explanation of exactly how the data is transformed such that the carpet intersections line up vertically. Many practitioners use a totally arbitrary shift because they don't know any better, resulting in a fancy but arguably less clear version of a multi-line plot.SkycraftAero (talk) 11:52, 4 November 2013 (UTC)

Under the "Variants" heading there could be a short summary table of the different types of variants and how many independent and dependent variables each one can handle.SkycraftAero (talk) 11:52, 4 November 2013 (UTC)

Nomenclature
I suggest adopting the nomenclature from Markus Schneider's "How to Generate Carpet Plots: A Guide to Creating Visual Trade Studies." That would be: SkycraftAero (talk) 12:02, 4 November 2013 (UTC)
 * "Four-variable carpet plot (true carpet plot)" for a conventional, two-axis, carpet plot with two independent variables and two dependent variables.
 * "Three-variable carpet plot (cheater plot)" for a plot with two independent and one dependent variables. This is also consistent with the ESDU 04008 nomenclature that uses the term "carpet plot" throughout and only discusses cheater plots.

Materials science
The plots that this reference generates are just multi-line plots. I'm inclined to remove the reference and the statement "Carpet plots have common applications within areas such as material science for showing elastic modulus in laminates" unless we can find an actual materials science textbook or something that calls those multi-line plots carpet plots. Otherwise, the article just needs a statement along the lines of "In material science, a type of multi-line plot depicting material properties is sometimes also called a carpet plot," which still needs a better reference.SkycraftAero (talk) 14:31, 4 November 2013 (UTC)
