• The Lower Histogram represents the entire capture. The gray area on the histo-
gram corresponds to the detail area.
Figure 6-1. Histogram Display and Button Controls
The vertical axis represents utilization in bytes per second. Data is loaded for
viewing in 10 MB increments. The Upper Histogram and the amount of data
selected for decode always spans an interval equal to a multiple of this 10MB
minimum.
You can use the buttons in the histogram display to locate more detailed areas of the
capture. The left mouse button can also be used to perform navigation operations.
Use the right mouse to select options that affect the display of the histogram graphs.
Use the Download button to actually decode your selection and have the decodes
appear in the Summary area of Capture View.
Note:
Capture files are now saved in a new file format with the
extension of .HST. Capture files created with previous releases
of Surveyor in .CAP format are automatically converted to the
new format when you open and save them. Captures are now
stored as one .HST file and a folder containing a series of .CAP
files that are part of the .HST file format. Do not delete or remove
the files within these folders, or portions of the capture file will
be missing.
Histogram Color Coding
There are some key concepts to understanding the color scheme for the histogram.
First, the Current Section(s) is the portion of the capture that is currently decoded.
Second, the Selected Section(s) are those section(s) spanned by the Capture
Selection Window in the Upper Histogram. This can be any region within the
capture. Once you press the download button, this section(s) is decoded and
becomes the Current Section.
