The Histogram operation calculates the histogram of a raster, polygon, segment or point map. Histograms list frequency information on the values, classes, or IDs in your map.
The results are shown in a histogram window as a table and as a graph.
Histograms of Value raster maps also contain summary information such as mean, standard deviation, and percentage intervals. The summary information is available in a histogram window as well as in the Properties of the histogram.
Dialog box options:
Input map: |
Select an input raster, polygon, segment or point map. Open the list box and select the desired input map, or drag a raster, polygon, segment or point map directly from the Catalog into this box. |
The output histogram always obtains the same name as the input map.
When you click the Show button, the dependent histogram will be defined, calculated and displayed in a table window. When you click the Define button, the histogram will only be defined; if necessary, it will be calculated later, for instance when the histogram is opened to be displayed.
