1. An analyte monitoring system, comprising:

  • an in vivo analyte sensor for positioning in fluid contact with interstitial fluid under a skin layer and configured to generate a plurality of analyte signals corresponding to a monitored analyte level in the interstitial fluid; and

    one or more processors configured to;

    receive one or more data packets including at least a current value and a plurality of prior values, generated from the plurality of analyte signals;

    determine a rate of change of the monitored analyte level based on the current value and the plurality of prior values;

    select, from a plurality of bins each corresponding to a respective rate of change, a bin for the current value and plurality of prior values based on the determined rate of change, each bin of the plurality of bins being associated with a position of a trend indicator on a display coupled to the one or more processors, each position of the trend indicator associated with a different rate of change for the monitored analyte level;

    dynamically modify an uncertainty parameter based on time spacing between the current value and the plurality of prior values; and

    output the trend indicator on the display at the position associated with the selected bin to indicate the associated rate of change when the dynamically modified uncertainty parameter based on the time spacing between the current value and plurality of prior values does not exceed a predetermined threshold level.
