I have several heatmap images, which I place in subplots stacked vertically. I’ve been using

ax = figure.add_subplot(nplots, 1, plotnum)

I’d like to annotate across all of the subplots by placing a vertical line (or vspan) across the entire figure-- to extend from the bottom figure all the way to the top, including the spaces in between. I thought I had seen an example of this somewhere, but couldn’t find it in the gallery. Any suggestions?

Maybe someone else knows of the “correct” way of doing this and we could get it added to the gallery?
