Viewing histograms and statistics

Histograms graphically represent the count of each pixel value in an entire or a selected region of a raster. The statistical information that you obtain from the pixel values can help you in your analysis of a geographical area.

You can access both histograms and statistics from the raster maps layer, and access the statistics from the file’s raster.

  1. In the Maps tree, select a raster map layer.
  2. In the Focus view area, use the Zoom tools to select the area for which you want to view a histogram.
  3. On the Layer menu, click Histograms. The Multi Histogram Display window appears if an RGB map layer is selected, otherwise, the Histogram Display window appears.
  4. Proceed to Viewing a histogram.
