Re: [Matplotlib-users] Normalizing Marker Size in Legend
Matthew, I think you're on the right track. You need proxy artists of some sort. You can create Line2D objects directly, never add them to the figure, and then use those to create the legend. An alternatively/hacky approach I often use is to the plot all the real data with '_nolegend' labels, get my current (or desired) axes limits, then plot the negative value of my data with the symbology I want in the legend and restore my original axes limits. This works for me b/c I'm always dealing with rainfall or water quality data, so negative values aren't really a thing for me to worry about. The concept is solid though: 1) plot the data (no labels) 2) record axes limit 3) plot fake data far away from real data with legend-appropriate symbology 4) restore axes limits 5) create legend.

[Matplotlib-users] Normalizing Marker Size in Legend
