1. A method, comprising: generating a plurality of three-dimensional representations of a surface of a body cavity by contacting a distal tip of a probe having an electrode on the surface of the body cavity and determining locations on the three-dimensional representations of the surface using the electrode, each representation being a different view of the same surface of the body cavity from a different viewpoint; measuring and recording respective time-varying electrical potentials at the locations on the three-dimensional representations of the surface of the body cavity in each of the different representations using the electrode; formulating a one-to-one correspondence between the locations on each of the different views of the three-dimensional representations of the surface of the body cavity and coordinates in a single two-dimensional coordinate frame representative of the locations; displaying a map of the one two-dimensional coordinate frame; and presenting respective graphic representations of the time-varying electrical potentials at positions in the map corresponding to the coordinates of the locations.
