Spaghetti, paella and alternatives: graphics for multiple series and groups

Nicholas Cox

London Stata Conference 2018 from Stata Users Group

Abstract: Spaghetti plots show many tangled lines (say for multiple time series or other functional traces) which are hard to distinguish and interpret. Paella plots show multiple point patterns for many groups, sufficiently mixed up that comparisons are made difficult. The talk surveys several tactics and strategies for better, friendlier comparisons. Devices range from showing data several times over to selection, smoothing and transformation.
