LabQuest can display a single graph, or two graphs. The two graphs share a common x-
axis column and range. Tap the triangle next to Graph 1 Y-Axis or Graph 2 Y-Axis to
show or hide the settings for that axis. If no column is selected for Graph 2, only one
graph will be drawn.
When you are done setting Graph Options, tap OK to return to the Graph screen.
