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.
