- Click the symbol to open the Format Symbol pane, where you can modify the symbol or pick a different one. Select a symbol style from the Gallery, or click the Properties tab to customize the current symbol. Click Apply when you are finished. Click the back button to return to the Symbology pane.
- Click the drop-down arrow next to the symbol to select a legend patch. A menu of defined patch shapes appears. Click a patch from the list to change the patch shape in the Contents pane and in legends in layouts.
Vary single symbol symbology by transparency, rotation, size, or color
You can add variation to the symbols by varying the transparency, rotation, size, and color of the symbols with attribute values. While all of these treatments can be applied simultaneously, be aware that too many visual variations make the layer very difficult to interpret. It is advisable to apply secondary symbology sparingly.
- On the Symbology pane, click the Vary symbology by attribute tab .
- Expand Transparency, Rotation, Size, or Color heading. In the case of polygon features, expand Outline width replaces Size and Rotation is not available..
