Dual Sided Histogram

A histogram is a special type of bar chart where all of the bars touch each other. On today's episode of Call for Help, I show a trick from Gerry Verschuuren's book, Excel for Scientists.

If your dataset includes data for both boys and girls, make one of the datasets be negative to have two histograms plotted on the same chart, with each histogram pointing the opposite direction.
