Confirmed, no query.
Example:
*RST; DISP:WIND:TRAC:Y:PDIV?; RLEV?

default trace. The response is
10;0.
DISP:WIND:TRAC:Y:AUTO ONCE; PDIV?; RLEV?
or:
DISP:WIND:TRAC:Y:AUTO ONCE, 'Trc1'; PDIV?; RLEV?
Autoscale the default trace and query the scaling parameters again. In general
both values have changed.
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:Y[:SCALe]:BOTTom <lower_value>[,
'<trace_name>']
Sets the lower (minimum) edge of the diagram area <Wnd>.
<Wnd>
Number of an existing diagram area (defined by means of
DISPlay:WINDow<Wnd>:STATe ON
). This suffix is ignored if the optional
<trace_name> parameter is used.
<WndTr>
Existing trace number, assigned by means of
DISPlay:WINDow<Wnd>:TRACe<WndTr>:FEED
. This suffix is ignored if the
optional <trace_name> parameter is used.
<lower_value>

to measure the input reflection
coefficient S11.
DISP:WIND2:STAT ON
Create diagram area no. 2.
DISP:WIND2:TRAC9:FEED 'CH4TR1'
Display the generated trace in diagram area no. 2, assigning the trace number 9
to it.
DISP:WIND2:TRAC9:Y:BOTT -40; TOP 10
or:
DISP:WIND2:TRAC:Y:BOTT -40, 'CH4TR1'; TOP 10, 'CH4TR1'
