Changing Symbol/Marker Outline Width in Julia Using PyPlot

Question

I'm trying to change the outline of the symbol (marker) inside a scatter plot in Julia using the PyPlot backend. I've tried edgecolor, edgewidth, edgelinewidth, markercolor, markerwidth, markerlinewidth and a variety of other key/values from various sources, but Julia/PyPlot recognizes none of these. How do I change the outline of the symbol/marker in a scatter plot executed in Julia using the PyPlot backend?

Answer 1

In Julia using the PyPlot backend, the correct key to manipulate the symbol/marker outline is markerstroke.... For example, markerstrokewidth=1 sets the outline of the marker to 1px, while markerstrokecolor="red" sets the outline color of the marker to red. I hope this helps.

Answer 2

For anyone reading this in 2022, PyPlot in Julia has completely changed. To change the edge size, the keyword is linewidths. In general, the repl is the best way to get up to date info. Just type ? (to get the help prompt), then PyPlot.scatter.
