There are typically many LegendClass objects in a LegendGroup. Each legend class contains a symbol and descriptive text strings form of a Label and Description. The Label appears in the table of contents, and the label and description can appear in the legend.
If a legend group is editable, then the symbol and label for the label classes contained by the legend group can be edited in the table of contents. Changes to symbols symbol will change the renderer's symbology and the map will refresh to reflect this change. Changes to labels will change the content of any legends that contain the layer.
The typically route for modifying renderer appeance through code is to go to the renderer objects themselves. For example, to change the simple renderer symbol, label and description fields, use the methods and properties of ISimpleRenderer in preference to the legend class object.
