The Graph Display contains the following information:

Tab Control - Control to switch between the Graph (Data and Events vs.Filter Control - Drop-down to select the filter mode (filter modes explained below).Major event key - Key for the major events, displayed as vertical lines on the graph.Robot Mode Key - Key for the Robot Mode displayed at the top of the screen.Hovering over event markers on the graph displays information about the event in the Messages window in the bottom left of the screen. Graph - This display shows graph data from the DS Log file (voltage, trip time, cRIO CPU%, Lost Packets, and robot mode) as well as overlaid event data (shown as dots on the graph with select events showing as vertical lines across the entire graph).It does not automatically locate the start of the match, you will have to scroll using the scroll bar to locate the beginning of the Autonomous mode. Match Length - This button scales the graph to approximately the length of an FRC match (2 minutes and 20 seconds shown).AutoScale - This button zooms the graph out to show all data in the log.This does not filter out data when the battery voltage being received is 0 due to a missing jumper on the Analog Module or no power provided to the Analog Module. The Voltage Filter filters out data such as CPU %, robot mode and trip time when no Battery Voltage is received (indicating that the DS is not in communication with the cRIO). Voltage Filter - This control turns the Voltage Filter on and off (defaults to on).

Scroll Bar - When the graph is zoomed in, this scroll bar allows for horizontal scrolling of the graph.

When hovering over an event on the graph this box changes to display the information for that event.
