Creating a scatter plot

You can use the Plot Ellipses options in the Class List Table to assess the separability of your spectral classes and to refine and edit your training sites.

A scatter plot should display an ellipse for each of the training classes. When there is overlap in several of the band combinations, you must adjust the threshold values.

From the Training Site Editor, click Tools and then click Scatter Plot.
In the Scatter Plot window, click in the Plot Ellipses column for each class that you want to include in the scatter plot. A check mark indicates a class has been selected. If you want to magnify a section of the graph, right-click on the area in the graph and click Zoom In.
