The Symbology functionality (from the My Layers window) is based on styles supported by GeoServer. Please see GeoServer User manual for more information.
Point symbology

You can Add or Remove a rule to the table.
To modify the graphic, click Graphic and select the symbol, color and opacity (Fig. 2 right).
Click Filter to modify a filter and select the property, condition and value (Fig. 2 center). If there is more than one condition in the Filter window, select the appropriate logical operator (AND, OR, NOT) from the drop-down menu. Use the 
icon to view the statistics of a selected property.
Click Apply for the new rules to take effect.
Coverage symbology
You can Add or Remove a rule to the table. To decide how to set up appropriate rules, it is often helpful to first look at the Statistics. You can then choose the color scheme representation under Type. The default Type is interpolation (ramp), with the others being Intervals and 'Values. For help in selecting the appropriate type, please refer to ColorMap type. If Intervals is selected, the first rule in the table should use the no data value of the coverage.
Click Apply to use the new rules.
Polygon symbology
You can Add or Remove a rule to the table. You can edit the Fill and Line of polygons and apply Filters for these rules using the standard operators (<,>,=<,>=,=). Complete changes by clicking Apply.
