A reduced-resolution version of the data (called a pyramid) is used to create the scatter plot when the Full Band option is enabled.

For example, if you draw a ROI around the entire scatterplot and the Full Band option is enabled, you may see some missing pixels, or holes, in the resulting class displayed in the Image window. The Full Band option provides a qualitative representation of the data, and it has limitations that you should be aware of. To include the full range of data in the Scatter Plot, enable the Full Band check box in the Scatter Plot Tool dialog. This is useful with large files, as it provides quick interactive response time.

If the bands do not contain dependent data, either band can be plotted on either axis and the Scatter Plot illustrates only the degree of correlation between the two bands. One band provides the x coordinates and the other band provides the y coordinates. The Scatter Plot Tool allows you to interactively classify two bands of raster data.
