The Analysis widget provides an easy way to use ArcGIS Online or ArcGIS Enterprise spatial analysis tools in your application. With 25 analysis tools, the same as those in the ArcGIS OnlineMap Viewer, you can configure one tool per widget or multiple tools in a widget. See the Perform analysis section of the ArcGIS Online help for an introduction to spatial analysis, the license requirements to access analysis tools, and details about the usage of each tool. If you're a developer, you can access these tools via web APIs. For more information, see Spatial analysis service REST API.
Analysis tools must have access to the data used by the layers and services on which you run them. If you use ArcGIS Server map or feature services, the analysis tools must have access to the data; therefore, the URL to the service must be a public URL or be on the same network as your portal.
Configuring the Analysis widget
Hover over the widget and click the Configure this widget button to open the configuration properties dialog box.
Tools are listed alphabetically in the configuration window. Choose the tools you want to include in the widget.
Click the settings icon next to your selected tool. The following options are available:
The tool display name—Provide your tool name.
Show help links in the widget—Controls whether to show help links in the widget.

Save the result in user's account—Controls whether to allow users to save the result in their accounts.
Allow to export results---Controls whether to allow users to export the result to CSV, Feature Collection or GeoJSON formats.
Repeat step 3 if you have more than one selected tool.
Click OK to save the configuration and close the window.
Using the Analysis widget
To perform analysis, the administrator of your organization needs to grant you certain privileges. To use any of the analysis tools, you need the following privileges:
Create, update, and delete content
Publish hosted features
Spatial analysis
Certain tools need additional privileges such as network analysis and GeoEnrichment. See Perform analysis for more information. If you don't have required privileges, the corresponding tools will not be available in the widget panel.
Verify that you are signed in to your organization with privileges to perform analysis.
Click the widget icon in your app to open the widget panel. If more than one tool is configured, choose tools one at a time to execute. If only one tool is available, it activates automatically. Click the help icon for information about the tool.
Note:
If you don't have required privileges to run a tool, the tool will not display in the widget panel. In addition to privileges, each tool has its own requirement for the layer or layers. If a tool does not have a required layer or layers in the map, the tool will be unavailable.
Also note that the Extract Data tool requires the extract capability be set in the service.
Choose an input layer from the drop-down list, configure the parameters for the tool, and click Run Analysis.
Tip:
