Viewing a histogram

You can view a histogram of a grayscale, pseudocolor, or an RGB map layer.

A histogram of the currently viewed area is first displayed. For an RGB map layer, a histogram is displayed for each RGB channel. At a glance, you can view the distribution of pixels and then select a histogram to view its statistics.

You can also view a histogram of a region that is under a bitmap mask.

In the Multi Histogram Display or Histogram Display window, click a histogram to view the histogram statistics and other details. The Histogram with Statistics window appears displaying the histogram of the content currently viewed in the Focus viewer.

You may now view the histogram statistics.
