 SmO2Graph is an advanced data field for endurance athletes that transforms your Moxy or Humon Hex muscle oxygen sensor into a powerful, real-time pacing and physiological guide. It goes beyond simple data display by using a sophisticated trend analysis algorithm to interpret your SmO2 dynamics, providing you with clear, color-coded feedback on your physiological state so you can optimize your effort, manage your energy reserves, and perform at your peak.

--  Description

  This data field provides a comprehensive, graphical view of your muscle oxygenation (SmO2) and total hemoglobin (THb) levels throughout your activity. It is designed to give you actionable insights into your body's energy systems, helping you understand the relationship between oxygen delivery and consumption in your working  muscles.

--  Key Features:

   * Real-Time Graphing: A clear, color-coded graph displays your smoothed SmO2 trend, allowing you to visualize your physiological response to changes in effort instantly.
   * Intelligent Trend Analysis: The core of SmO2Graph is a state machine that analyzes your SmO2 data to identify four distinct physiological states, each represented by a unique color on the graph:
       * Red (Strong Decline): A rapid drop in SmO2. This indicates a heavy reliance on anaerobic energy and warns that your current effort is unsustainable.
       * Yellow (Weak Decline): A slow, steady decrease in SmO2. You are pushing hard and approaching your limit, a state that can be held for a limited time.
       * Green (Stable): Oxygen delivery is meeting muscular demand. This is your sustainable, steady-state effort for long durations.
       * Blue (Recovery): SmO2 is actively rising, showing that oxygen delivery is exceeding demand. This confirms you are recovering effectively during easier periods or rest intervals.
   * Essential Data at a Glance: The data field displays your current smoothed SmO2 value, session MAX and MIN SmO2, and current THb concentration.
   * Live Configuration: All algorithmic settings, including smoothing windows and the thresholds that define each trend state, can be adjusted live during an activity through your Garmin Connect app settings, allowing you to fine-tune the data field to your unique physiology.

  By interpreting these color-coded states, you can make smarter pacing decisions, avoid "burning matches" unnecessarily, ensure your recovery intervals are effective, and truly dial in your performance for any endurance event.

On the smaller Datafields will revert back to displaying just numbers.
