Histogram Button Controls

Histogram controls allow you to focus on a smaller area of the capture, change the appearance of the graph, and load sections of the capture to the decode area. These controls are also available form the Histogram… menu.

Scroll Back, Scroll Forward

Slow scroll forward and back. Scrolls through the data in the Upper Histogram one section at a time. Buttons are grayed when you reach the end of the data shown in the Upper Histogram. Use the CTRL + –>and CTRL + <– key combinations to perform the same scrolling actions as the Scroll Back and Scroll Forward buttons.

Scroll to Beginning, Scroll to End

Fast scroll forward and back. Scrolls to the beginning/end of the data in the Upper Histogram. Buttons are grayed when you reach the end of the data shown in the Upper Histogram.

Zoom In

Zooms in to show finer granularity of the capture. The amount of data viewed is reduced between 20% and 1%, depending on the setting for the Zoom Factor. Zooming ceases when the Upper Histogram contains 2 capture sections (20MB of data).

Zoom Out

Zooms out to show a larger scope of the capture. The amount of data viewed is increased between 20% and 1%, depending on the setting for the Zoom Factor. Zooming ceases when the Upper Histogram contains all capture sections within the window set by the extent marks within the Lower Histogram that define the contents of the Upper Histogram.
