Styling Polygon Data
Style polygon features.
Polygon features can be styled to adjust fill color, outline stroke width and color, and opacity. Symbology for polygons also include controls to normalize numeric data by acre and apply 3D extrusion; for details on using these controls, see Applying 3D Extrusion.

Polygon Data Styling Options

Fill ramp. Select a color ramp to apply a range of colors to the value classes. Colors for individual classes can be modified after a ramp is selected. If the layer comes loaded with default symbology, or if you modify colors after a ramp is selected, the stroke ramp control will read Custom ramp.
The available color ramps vary for categorical and numeric data types. The options are the same as those shown previously for point fills. The Flip toggle reverses the application of the ramp colors — for example to move from dark to light colors, rather than light to dark, as values ascend.

Classes. For categorical columns, this simply lists the unique values as represented in the data, not including null values. For numeric columns, this also includes the controls to classify data. See Classifying Data for details on classifying numeric data.
You can vary the colors for each value or value class using the Fill ramp, and/or set them individually. The Classes options for categorical and numeric data are shown below.
Styling options for categorical (left) and numeric (right) data
Select the color swatches to edit the colors for individual values. When you click on a fill color swatch, a color selection panel appears. You can choose from the available colors, or enter a hex code or RGB value for a custom color.
Stroke. Appears as a combined color and width control when symbolizing classes. The same width and color settings are applied to all classes. Stroke width options include 0.5, 1, 2, 4, or 6 pixels. You can choose from the available colors, or enter a hex code or RGB value for a custom color.
Stroke options
Stroke color. Appears as a separate control when using a single symbol for all features. You can choose from the available colors, or enter a hex code or RGB value for a custom color.
Stroke width. Appears as a separate control when using a single symbol for all features. Stroke width options include 0.5, 1, 2, 4, or 6 pixels.
Opacity. Opacity applies to the point and its outline. Drag the slider or click along the line to choose an opacity level.
Opacity control
Save. Click Save to save any edits you have made. The button will be inactive if you have not made edits.
If you navigate away from the Symbology Editor without saving (for instance, by selecting another layer), you will lose your active settings.
Discard. Click Discard to abandon any edits you have made. The button will be inactive if you have not made edits.
Restore Defaults. Click Restore Defaults to revert to default symbology settings, if they exist. The Base Canvas, scenario layers, analysis layers, and many reference datasets come loaded with default settings for commonly used columns. User-uploaded layers do not have associated default settings.
