The start date/time is the left edge of the graph. The Window setting determines how much time is shown from that start. Use the buttons, mouse wheel, drag, or arrow keys to move through time.

The graph min/max is the normal vertical range. The graph expands only when visible values or limit lines fall outside that range. The curve uses the sharp WebGL render path and quietly prefetches neighboring time ranges while you scroll.

Colors identify sensors. Shape and line style identify the data source.

← / → pan half a window. + / − zoom. Home jumps to now.
