1. A continuous glucose sensor system, the system comprising:

  • a sensor configured to measure a glucose concentration in a host;

    sensor electronics configured to process continuous glucose sensor data from the sensor; and

    a user interface configured to display information associated with the continuous glucose sensor data, wherein the information comprises one or more prospectively calibrated glucose sensor values and a plurality of different graphical representations indicative of smoothed glucose trend information over a plurality of different predetermined time periods to provide a plurality of different resolutions of the smoothed glucose trend information, wherein the user interface is configured to selectively display the plurality of different graphical representations responsive to a user selection, wherein the smoothed glucose trend information comprises a plurality of time-spaced sensor values, wherein the sensor electronics are configured to smooth the plurality of time-spaced sensor values associated with a predetermined window of the continuous glucose sensor data, and wherein the user interface is configured to display sensor data or not based at least in part on a level of stability of the continuous glucose sensor data, wherein the level of stability is based at least in part on an evaluation of a sensor sensitivity associated with signal strength with respect to glucose concentration.
