1. A method of displaying impedance information of an implantable medical device, the method comprising:

  • receiving a plurality of impedance values over a period of time for each of a plurality of channels, wherein the channels each include an electrode contact on an implantable lead;

    determining, from the plurality of impedance values, a respective worst case impedance value during the period of time for each of the channels, wherein the respective worst case impedance value is an impedance value that has a greatest amount of deviation from either a specified upper threshold or a specified lower threshold;

    displaying, via a graphical user interface of a clinician programmer, a graph that illustrates a variation of the impedance values over at least a portion of the period of time for one or more of the channels; and

    displaying, via the graphical user interface of the clinician programmer, a visual landscape that is representative of the respective worst case impedance value for each of the plurality of channels.
