I've seen a plug in that tracks players throughout UHC matches and you can look at later following their actions and seeing icons pop up as they mine etc.

However I imagine it would be more complex with the variety of actions happening at once specific to RFW such as cannon building and chest supply runs

Something along the lines of this XKCD comic, plotting progress through the map of each player against time, would be quite a neat thing to do.

It'd work well for mirrored-lane-style maps, since both teams could be shown on the same graph, and reducing progress along the map to one dimension is simple. It would be less apt for the spiral-style maps.
