Right Mouse Options in the Histogram
A right mouse brings up a menu of display options for both histograms. Depending
on the data, changing the settings can give you a better visual display of transition
points and high/low values.
• Line Graph or Stair Step
A line graph smooths out visual transitions for low to high and high to low. Stair
Step is the default.
• Linear Scale or Logarithmic Scale
Linear scale can show larger visual differential between high and low values
than the logarithmic scale. Linear Scale is the default.
• Options
Brings up the dialog box to set the configuration options for the histogram. See
“Histogram Options” on page 4-4 for information on the histogram configura-
tion options.
Saving Portions of the Data
You can save all or part of a capture using the histogram. Use the Save Current
Selection... option from the File menu to save the Current Section of the histogram.
The Current Section contains the packets that are currently decoded and displayed in
the Summary area. You can also save a specific set of frames within the Current
Section.
Use the Save Histogram... option from the File menu to save the entire capture or a
large range of the data. To save a range, select the Range of downloaded sections
