1. Apparatus for displaying information, comprising:
- a probe comprising a proximal end and a distal end, the distal end of the probe configured to be inserted into a body of a subject and comprising;
a force sensor arranged at the distal end of the probe, the force sensor configured to sense a force signal indicative of a force exerted by the distal end of the probe on tissue of the subject, the force signal comprising a first indication of a magnitude of the force and a second indication of a force-direction of the force; and
temperature sensors arranged at the distal end of the probe, the temperature sensors configured to sense temperature signals of temperatures in a vicinity of the distal end of the probe;
a display screen; and
a processor configured to receive the force signal and the temperature signals, to display on the display screen in a single map a graphical representation showing a distribution of the temperatures with a vector representation of the force superimposed on the distribution of the temperatures;
wherein the vector representation comprises the first indication of a magnitude of the force and the second indication of a force-direction of the force.

Abstract
A method for displaying information, including receiving measurements, with respect to an invasive probe inside a body of a subject, of probe parameters consisting of a force exerted by the probe on tissue of the subject and temperatures measured by sensors of the probe. The method further includes, responsively to the measurements, displaying in a single map on a display screen a graphical representation of a distribution of the temperatures in a vicinity of the probe and superimposing thereon a vector representation of the force.
