The workout graph gives a preview to the entire workout by color coding steps of the workout according to your zones. The workout graph zooms to the current interval for the first 30 seconds, then shows the current and next 4 intervals; power or heart rate values are overlaid on top of the targets in the graph. The workout graph can be found under the Workout category of the data fields menu.
