Juxt Array Label Field

Controls: File Menu >> Juxt Dialog >> Label
Macro: JuxtLbl

When Array is on, a label can be shown on each trace for identification. This control allows you to select a Field to be used as the label; any text or value in that field on the original saved trace will be used as the label. That text or value will also be used for sorting the traces if Sort is active.

You can use macros to send relevant test parameters like SPL or frequency to particular Fields when the traces are being recorded. (See the discussion under Fields.)

You can edit a Field after the trace has been saved to Juxt Array memory. Make sure that either Array or the single Trace Select button is active, then scroll the up/down arrow buttons to select the desired trace, and edit the Field normally.

Use the horizontal arrow buttons to select the desired label. The options (left to right) are: None, Field 1 to Field 6, Trace number, Time, Date, Time UTC, or Date UTC.

If the chosen Field of a given trace is empty, the trace number is shown instead.

Trace number refers to the sequence in which the traces were originally saved via the New button. This sequence is preserved when you Save the array to a .JXT file and later Load it again. If an array is in memory and you load another while retaining the first, the added traces are shown with numbers continuing from the initial series.

When a trace is saved, either to a .DQA file or directly to Juxt memory, a "timestamp" is included. The Time and Date label options report that value in local time; the UTC versions report it in Coordinated Universal Time, the international standard that replaced the former Greenwich Mean Time (GMT).

If the array contains traces acquired from different locations around the world, the UTC options will allow absolute comparisons. UTC may also be preferable even if all traces are from your own location, if they were acquired at widely spaced dates and Daylight Savings Time may have been in effect for some of them.

Date or Time label options use the formats specified in the Date/Time Preferences menu.

Labels are shown at the right end of each trace by default. You can move a label on a Selected trace by holding down the CTRL key and dragging it with the mouse. As you drag horizonally, the label also moves vertically to keep its lower left corner on the trace.

If the Selected trace has two or more channels active and their labels overlap, CTRL-drag will move the first channel it finds in this list: L.In, R.In, L.Out, R.Out. After you move that label, you can move each subsequent label in turn.

Label positions are preserved when arrays are saved to and loaded from .JXT files.


Macro Notes:

JuxtLbl=0 sets None.

JuxtLbl=1 sets Field 1, through JuxtLbl=6 for Field 6.

JuxtLbl=7 sets Trace number.

JuxtLbl=8 sets local Time.

JuxtLbl=9 sets local Date.

JuxtLbl=10 sets Time UTC.

JuxtLbl=11 sets Date UTC.

JuxtLbl=>1 scrolls one selection to the right, JuxtLbl=>-1 scrolls one selection to the left. Only +/-1 step is accepted.
