After I create a classification image through the'Classification Workflow', the default simply names the classes as Class 1,Class 2, etc., and assigns them default colors. I need to change the names and colors of these classes, so I right-click on the classified image in the "Layer Manager" and click on 'Statistics for all classes...' It brings up the 'Classification Statistics View' dialog box, in the 'Curve' tab. I can change the name and color, but it has no effect on changing the name or color on the displayed classification image. What am I doing wrong?
