1. A glucose sensor system for monitoring glucose concentration in a biological sample of a host, the system comprising:

  • a continuous glucose sensor configured to produce sensor data indicative of a host'"'"'s glucose concentration; and

    an electronics module configured to receive sensor data from the continuous glucose sensor, wherein the electronics module comprises a processor configured to process sensor data received from the continuous glucose sensor, to calibrate the sensor data, and to determine a rate of change of the host'"'"'s glucose concentration based on the calibrated sensor data; and

    a display;

    wherein the system is configured to present, on the display, a rate-of-change icon in at least three different configurations, and wherein the system is configured to select a configuration in which to present the icon on the display from the at least three different configurations based on the determined rate of change in the host'"'"'s glucose concentration.
