Color plots, integrate only flight portion of data.

Telemetry files have piles of pad data which shouldn't be integrated
into the velocity data as it tends to generate huge values from the
noise of the sensor.

Also make the data lines colored to keep them visually distinct from
the rest of the plot image.
