Overlay/Nooverlay

Displays two or more SCANs on top of each other.

Format:

SPECTRA> ov$*$erlay
SPECTRA> ov$*$erlay id1
SPECTRA> ov$*$erlay id1 id2
SPECTRA> ov$*$erlay/x id1 id2
SPECTRA> ov$*$erlay/y id1 id2

Description:

Sets the overlay bit. The drawing of the axes is suppressed for id1, the TEXTs that belong to id1 are deactivated.

If id2 is supplied, id1 receives the window limits from id2. This is repeated for subsequent autoscale and display commands. The qualifiers /x and /y specified whether the limits of one axis only are copied.

If there are no parameters, the command affects all active queue elements. SCANs which have the overlay bit set are marked with an 'o' in the show list. SPECTRA activates the GQE while setting the overlay bit for a single GQE. This command is especially useful, if the SCANs window limits but the user wants to see them in one frame.

e.g.:

SPECTRA> over bpu1

Format:

SPECTRA> noov$*$erlay [id]

Description:

Clears the overlay bit.
