Abstract

Visualizing data with more than two variables is not straightforward, especially when some variables are categorical rather than continuous. My hammock plots are one option to visualize categorical data and mixed categorical/continuous data. Hammock plots can be viewed as a generalization of parallel coordinate plots, where the lines are replaced by rectangles that are proportional to the number of observations they represent. I will introduce my Stata program for hammock plots and give several short examples where I have found them useful.
