Distributions of non-numeric data, e.g., ordered categorical data, look similar to Excel histograms. If you have a bin width of 20, and the bin value is 40, the corresponding frequency is all values between 20 and 40. There must be a row containing the name of the histogram. And this produces a nice bell-shaped normal curve over the histogram. This is done by creating bins of a certain width and counting the frequency of the samples that fall in each bin. Simply use the protocol in Histograms Using Excel XY Charts with an area chart, and format both the fill and border of the area chart series as desired.
