Set transparency by attribute


You need the following account and license types to use this workflow:

  • Microsoft license—You need a Microsoft 365 license, with the Contributor role or higher, to set transparency for map features.
  • ArcGIS account type—Standard users can perform the functions of this workflow; you do not need to sign in.

You can set the transparency per feature if the data is numeric or date and time.


This workflow is not available for ArcGIS for Power BI features.

See Data styles to learn about data style options and Smart map styles to learn about smart map cards.

Setting the transparency based on attribute values in the data allows you to vary the amount of transparency that is applied to each location based on a numeric attribute. For example, if the layer contains sales data, you can style the data according to the business type and adjust the transparency proportional to annual sales.

To apply transparency, complete the following steps:

  1. Follow the steps in the Apply a style workflow for your component:
  2. Choose a smart map card.
  3. Hover over the style card and click Style options Style options to customize the look of the layer.

    The style options appear.

  4. Expand Transparency and turn on the Enable transparency toggle button.

    Options for configuring transparency by attribute appear.


    The Transparency option is not available for some smart map cards, such as heat map.

  5. To configure transparency, do any of the following:
    • From the Field drop-down menu, choose a numeric or date attribute to use as the basis for the transparency.
    • From the Divided by drop-down menu, choose an attribute to standardize or normalize the data, such as population by area or costs by total population.
    • Adjust the position of the slider handles to change how the transparency gradient is applied.

      You can also click the numeric values next to the slider handles and type the values.

    • For Transparency range, adjust the percentage of transparency for the high and low ends of the ramp. Zero percent transparency is a solid color (fully opaque).
  6. Click the Back button Back to close the pane and view the Layers list.
