1. A method for improving navigation of data collected from a heart of a patient, the method comprising:
recording a point-list, wherein each entry in the point-list includes a location in the heart and a measurement acquired by an electrode of a catheter placed at the location in the heart;
rendering a representation of at least a portion of the heart;
selecting on the representation one or more anchor points associated with a region of interest in the heart;
computing, for each entry in the point-list, a distance between the location associated with the entry in the point-list and the selected one or more anchor points;
manipulating one or more entries in the point-list based on the distance computed; and
overlaying graphical elements on the representation, wherein the graphical elements are representative of a result of the manipulating.
