When either the Capture Selection Window or the Capture Detail Window spans these sections they will appear in a darker shade of purple. When either window does not span the last downloaded section, this section will appear in a lighter purple (magenta).

Five of the total seven sections available in the capture are shown in the Upper Histogram. The sections that are not the Current Section or the Selected Section are available from the disk cache.
