The operator has selected three separate channels to analyze in time. The green represents the signal strength of the telecom system. The purple and pink bars represent which channel, S-Band Carlock or S-Band Signal Strength, the spacecraft was locked into at a certain period in time.
Collapsing channels into a single view
When the operator collapses the two channels that were locked together, the operator can see the relationship of signal strength to the S-Band Signal Power channel.
Saving to a library
This is a set of channels the operator references frequently. So they save it to their library.
