Histogram Options
Select
Capture View Options→Histogram… from the Configuration menu and select
tabs at the top to set up the histogram display.
For the histogram, you can set the colors for the display from the
Colors tab.
However, it is recommended that you maintain the default colors. You can also set
the Zoom Factor from the
Zoom Options tab. The Zoom Factor controls how fast
you can zoom in and out the view of data. You can also the set the download size
from the
Sections tab. This controls how much data is downloaded from external
capture devices when the data is requested by pressing the down load button in the
histogram window. See “Histogram Options” on page 4-4 for complete information
on setting up capture view histogram options.

Configuration→Capture View Options menu. Selecting Expert Settings from the
Configuration→Capture View Options menu brings up the dialog box to select
expert settings for system.
Using the Histogram Control
The histogram control graphically represents the entire capture from start to end. It
also allows you to expand and collapse the view of the histogram to look at a
graphic display of a detailed portion of the capture.
The Surveyor histogram has two graphs:
• The upper part of the histogram shows a detail area of the capture. The purple/
magenta area in the Upper Histogram corresponds to the events shown in the
Summary area (listing of decoded events).
