Are there graphing techniques (certain kinds of plots) that are similar to the Edward Tufte's box plots - shown below - but that consider the distribution of the data points?
But instead of a black line traveling vertically, I want a colored line (say red) where the intensity of the redness changes in relation to the frequency of data points at the location. What I am picturing exactly is a vertical red line that does from 1% to 99%, with horizontal grey lines at 25% and and 75%, a black line at the median, with the color intensity of the vertical red line changing with respect to the number of times each data point along the vertical location was measured.
Any ideas?
Thanks, Tom
