Hi, In trying to add a symbol for an empty wind barb, I ran into problem. Traditionally, a smaller, non-filled circle is used for low wind speeds when doing a barb plot. I can draw the circle easily as a polygon, using CirclePolygon from patches, but unfortunately, the fill color for this polygon ends up being the same as the color of the flags on the barbs. Therefore, as currently implemented, the only way to have unfilled circles is to have unfilled flags.
The only technical solution I can think of here is to have separate collections for the circles and the polygons. Unfortunately, I have no idea how to begin to do that within a class that inherits from collections. Another option would be to somehow manually set the fill colors on the circles after the collection is initialized. Anyone have suggestions on how to make this work, or maybe a better technical solution. Jeff, how aesthetically displeasing do you think it would be to have small (possibly colored) circles to represent the low winds instead of the traditional (somewhat larger) hollow circle? It would make it impossible to do sky cover in a traditional surface map, but maybe Z-ordering could be used to hack around it.
