Adds toggles to the User Interface section of the app Settings that
allow the user to display or hide the three series available in the
chart: Elevation, Speed/Pace, and Heart Rate. As a user of a heart rate
monitor primarily during strength workouts and combat sports, the
distance and elevation graphs are not helpful to me - in addition, their
scale means that I am not able to easily see my exact heart rate. This
should allow users in a similar situation to better determine exactly
what is most helpful for them to be seen on the graph.
Also updates heart rate series possible intervals - the smallest interval
was 25, which was too low for most zone 1 cardio charts - if your heart
rate goes from 70 to 125, with a 25 interval, most of the chart will be
whitespace.
