The parameter Graph displays 3 user-selectable variables and has two y-axis scales (one on left, one on right side of graph). The Graph has an interactive, draggable vertical slider synchronized with “current time” of all displays (e.g. Map, Video, etc.) and color-coded event marks overlayed on the primary variable trace. Event marks are filtered for display per the Prefs->Events tab. Events are mouse-sensitive and display event statistics (name, max value of primary variable that triggered the event, duration, etc.) upon mouse-over. There will be a numeric readout that displays the current value of each selected variable as well.
A Prefs->Events command allows the user to change colors associated with event types (Routine, Advisory, Caution, Warning and Custom). Graph can be zoomed and panned, and restored to the default attributes. .
There are currently two initial versions of the graph implemented: 1) based on dyGraph and 2) based on Google Map API. Both are functional but lack certain features as defined in the attached doc.
