I am working on visualizing ~4100 buffered point features. The shading of the buffers is keyed to a field in the data. Because the buffers overlap, I turned on multiply in the new feature blend mode options. I like the visual result, but what seems to be missing is an ability to generate a meaningful legend for the resulting image. Are there any workarounds for this? Is the only alternative to venture down the path of polygon intersects and symmetrical difference operations?
