About using a single symbol to draw features
Mapping and visualization
Often, seeing where something is—and where it isn't—can tell you exactly what you need to know. Mapping the location of features reveals patterns and trends that can help you make better decisions. For example, a business owner might map where his customers live to help decide where to target his advertising.
The easiest way to see where features are is to draw them using a single symbol. You can draw any type of data this way. When you create a new layer, ArcMap draws it by default with a single symbol.
Example single symbol map
On a map that uses a single symbol to represent cities, you could easily see where people live and conclude that some areas are more densely populated based on the number of cities clustered together.
How to draw a layer using a single symbol
- Right-click the layer you want to draw with a single symbol in the and click Properties.
- Click the Symbology tab.
- Click Features in the Show box on the left side of the dialog box.Because Single symbol is the only option under the Features renderer, ArcMap automatically selects it.
- Click the Symbol button to change the symbol.
- Click a new symbol or change specific properties of the symbol in the Symbol Selector dialog box.
- Click OK on the Symbol Selector dialog box.
- Type a Label for the feature. The label appears next to the symbol in the table of contents.
- Click OK.
- To quickly change the symbol that features are drawn with, click the symbol in the table of contents to display the Symbol Selector.
- To quickly change the color of a symbol, right-click the symbol in the table of contents to display the Color Selector.
- Click Description on the Symbology tab of the Layer Properties dialog box if you want an additional description of your layer to appear in your legend. You can press the Ctrl and Enter keys together to insert a line break in your description.
- If you are symbolizing point features, you can apply an angle to the symbols to make them rotated. See Rotating point feature symbology for more information.
