Use
File → Load .TIM file
to read the .TIM file you just saved. Now you should have two
copies of the same plot in memory. At the left edge of the legend table entry for the most
recently-initiated or loaded plot, you’ll see a black triangular cursor, indicating the plot
that’s currently selected for editing, browsing, or other forms of control interaction in
TimeLab. In the table below, the most-recently loaded plot has been automatically selected:
If the measurement is still in progress, you can left-click on the original plot’s row in the
legend table or press the
Up arrow key to re-select it, then switch to the p)hase or
f)requency difference views to watch its phase record continue to grow while the saved
copy remains unaffected.
For “power users,” three of the most common commands in TimeLab are Display → Browse plots one at
a time (b) , Display → Overlay all loaded plots (o) , and Display → Toggle visibility of selected plot (v) .
Like many other commands, the b , o , and v commands operate on the so-called “selected” plot as
described above. If you’ve followed along with the suggested command demonstrations above, then
you should have two (or more) plots loaded, and you can experiment with these concepts.
•
First, select any desired Measurement view and press the b key to enter Browse mode.
Observe that only one of your plots is now visible.
• Furthermore, notice that two things happen when you press the Up- or Down-arrow keys
( Display → Select next plot in chart / Display → Select previous plot in chart ). The small black
triangular cursor at the leftmost edge of the legend table moves up and down, and the plot
that it points to becomes visible. (You can also select a new plot by left-clicking on its row in
the table.) In
Display → Browse mode, entries in the legend table corresponding to all of the
unselected plot(s) are grayed out, and those plots aren’t shown in the graph.
• You can put things back to normal by pressing o to return to Display → Overlay mode. The
idea of a “selected” plot still exists in Display → Overlay mode, but it no longer determines
which plots are visible in the legend table and graph areas. In Display → Overlay mode, all of
the loaded plots are visible, all of the time, unless individually hidden with the
Display → Toggle visibility of selected plot (v) function.
• To avoid confusion, the Display → Toggle visibility of selected plot (v) function doesn’t do
anything in Display → Browse mode. But in Display → Overlay mode it does just what it
sounds like – it toggles the visibility of the selected plot in both the graph area and the
legend table. This panoply of options may seem confusing at first, but it’s nothing compared
