1. A method for monitoring a medical procedure, comprising:
applying energy to a probe that is in contact with tissue in a cavity within a body of a living subject so as to ablate the tissue;
while applying the energy, receiving, by a processor, signals from a location transducer in the probe, which are indicative of a location of the probe in the cavity;
processing the signals so as to derive three-dimensional (3D) location coordinate points corresponding to the location of the probe at a sequence of times during which the energy was applied;
rendering to a display a 3D representation of the body cavity, and superimposing on the 3D representation visual indicators corresponding to the 3D location coordinate points at the sequence of times together with a linear trace connecting the coordinate points in accordance with the sequence;
counting, during the sequence of times, respective numbers of instances of each of the 3D location coordinate points; and
rendering a bounding sphere having a surface that encloses the visual indicators, wherein rendering the bounding sphere comprises centering the bounding sphere at a graph location in the 3D representation corresponding to 3D location point having a highest number of the instances.
