1. A computer implemented method, comprising: storing electroanatomic data in memory, the electroanatomic data representing electrical activity for an anatomic region within a patient's body; selecting a time interval for the electrical activity in response to a user selection, wherein the user selection specifies the interval based on interacting with a representation of a waveform of electrical activity for a given location of a plurality of locations for the anatomic region; and responsive to the user selection of the time interval, automatically generating a visual representation of physiological information for the user selected time interval by applying at least one analysis method to the electroanatomic data for each of the plurality of locations of the anatomic region within the user selected interval, the visual representation of physiological information for the user selected time interval being spatially represented on a graphical representation of at least a portion of the anatomic region.
