Have you ever tried making small multiples in Excel? I have. Several times. It's possible. Everything is possible in Excel, but some things just take forever. And when you're done and realize you'd like to change it just slightly, it takes forever again.
Countless times I was in a situation where small multiples of, say, 12 waterfall charts would be perfect for my customer's dataset and intended message, but I dismissed the thought in a split of a second. Imagining I have to produce a bunch of Excel formulas for dummy chart series, apply all those hacks and tricks to make the charts effective and visually correct, adjust the labels, apply the design, etc. And do all that 12 times for 12 charts, take care of proper scaling, solve the labelling of categories based on the position of charts within the matrix, ... Huh, just forget about it. It's frustrating.
