Using LUCID
3. The number of bytes processed so far in the current
session. The current session includes all runs since the
last Build operation.
4. The approximate rate at which data is being acquired,
analyzed or recorded.
Figure 2.14 shows some examples having different status labels
being displayed.
Figure 2.14. Different Status Labels
After a status button has been selected three times, it will cycle
the label around to the initial status message. The process of approximating the data rate is done every 5 seconds (roughly), so
initially, it might say Inadequate Statistics if it hasn’t had enough
time to make the calculation.
The Histogram Windows
The most frequently used feature of the LUCID program itself is
the display of histograms. Histograms are described in detail under LOOKER Histograms on page 4-26, and the user is encouraged to read that section if the topic is not familiar to them.
Histograms are displayed by selecting variable names from the
View Data sub-window, as described under The View Menu on
page 2-14. Each histogram is placed in a separate window, and
can therefore be individually resized or modified. They can also
be closed to an iconic state.
Each histogram window has a set of four menu buttons which allow manipulation of the data or its representative image. The
window depicted in Figure 2.15 show the File, View, Edit and
Print menu buttons which are associated with every histogram.
Many features within these menus are used quite often, and LUCID understands several different keystrokes to perform the
same functions as various menu selections. Users will most
probably use these simple keyboard shortcuts more often than
