This is an example representation of a workbook, retrieved using the [Get a workbook](/reference/get-workbook) endpoint with the query parameter `includeContents=true`. Representations like this one can be used to create a workbook from code using the [Create a workbook](/reference/create-workbook) endpoint. Each page in this example library includes the code representation of the workbook and step-by-step instructions to create it in the Sigma UI. Consult this example and others in the [Workbook representation example library](/docs/workbook-representation-example-library) to: * Troubleshoot the formatting of a particular feature in code representation * Relate a feature from the Sigma UI to its representation in code * Provide context to AI tools used to create workbooks from code > **Warning** > > This example representation cannot be used as-is. All identifying details, such as IDs, names, and URLs, have been replaced with randomized ID values or generic substitutions. The format of these contents, like the length of ID values, is preserved for demonstrative purposes. However, this representation cannot be directly used without modification to the base URL, connection details, and more. For more information, see [Create and manage workbooks from code](/docs/manage-workbooks-as-code). ## System and user requirements To complete the steps in this example, you must meet the user requirements listed below for creating the workbook in the UI and creating it from code. The ability to create this workbook in the Sigma UI requires the following: * You must be assigned an [account type](/docs/account-type-and-license-overview) with the **Create, edit, and publish workbooks** permission enabled. * You must have access to a connection to a data platform. The ability to create a workbook from code requires the following: * You must be assigned an [account type](/docs/account-type-and-license-overview) with the **Create, edit, and publish workbooks** permission enabled. * You must have developer credentials for the Sigma API. For more information, see [Get started with the Sigma REST API](/reference/get-started-sigma-api). This example uses a table from the [Sigma Sample Connection](/docs/sigmas-sample-connection). Your organization might have disabled access to the Sigma sample connection. If so, you can contact an admin to enable it, or use a table from another connection to follow along with this example. ## Create the example workbook in the Sigma UI This example shows a workbook with a top N control that limits a bar chart to the highest-ranked stations. To create this workbook in the Sigma UI: 1. Go to the **Home** page. 2. Select ![](https://sigma-docs-screenshots.s3.us-west-2.amazonaws.com/Icons/button-add.svg) **Create new** > **Workbook**. A new workbook opens. 3. From the **Add element** bar, select **Data** > **Table**. 4. In the **Select source** modal, search for the table `TRIP` in the `EXAMPLES.BIKES` schema. 5. Select the table to add it to the workbook. The table appears in the workbook. 6. With the table selected, select ![](https://sigma-docs-screenshots.s3.us-west-2.amazonaws.com/Icons/add-dependent.svg) **Create child element** > **Chart**. A new bar chart element appears on the workbook canvas. 7. In the editor panel, select **Properties** and configure the bar chart with the following settings: | Option | Setting | | :--------- | :------------------------ | | **X-axis** | *Start Station Name* | | **Y-axis** | Count of rows (`Count()`) | 8. From the **Add element** bar, select **Controls** > **Top N**. 9. Select the control, then in the **Properties** tab of the editor panel, enter `Row-Count` as the **Control ID**. 10. Select **Targets**, then add the bar chart as a target, ranking on the count of rows. 11. Set the control value to `10`. The bar chart now shows only the 10 stations with the most trips. 12. In the document header, select **Save as**. 13. Enter a name for the workbook, such as `top-n-control`. 14. Select **Save**. ## Get a code representation of this workbook To get a representation of this workbook, follow the steps in [Get the code representation of a workbook](/docs/get-the-code-representation-of-a-workbook). The code representation of this workbook appears like the following: #### YAML representation ```yaml workbookId: 4dad2986-ce83-4960-aa06-e9ab85a0bcc1 workbookUrlId: 9xslXTTIQrh6bpy0VAq3GZ createdBy: uO2R8UziJdi0Y4mj4TIJZ9RnvIh4T updatedBy: uO2R8UziJdi0Y4mj4TIJZ9RnvIh4T createdAt: '2026-09-01T14:53:44.615Z' updatedAt: '2026-11-03T20:03:26.798Z' name: top-n-control url: https://aws-api.sigmacomputing.com/org-name/workbook/9xslXTTIQrh6bpy0VAq3GZ path: My Documents/ latestVersion: 3 ownerId: uO2R8UziJdi0Y4mj4TIJZ9RnvIh4T isArchived: false contents: schemaVersion: 1 elements: - id: OetAfG8 kind: table source: connectionId: ff0f3b81-a3e2-489c-b95e-846bdbd5f6d2 kind: warehouse-table path: - EXAMPLES - BIKES - TRIP columns: - id: MjRZA0G6v formula: '[TRIP/Id]' - id: bBxKd5WVwd9 formula: '[TRIP/Duration]' - id: ExLXa3zphJn9 formula: '[TRIP/Start Date]' - id: pH9xdreYrmVM formula: '[TRIP/Start Station Name]' - id: 1JIJ5iqQt6 formula: '[TRIP/Start Station Id]' - id: wukvg6KLYr formula: '[TRIP/End Date]' - id: vadWwbDVrE formula: '[TRIP/End Station Name]' - id: OdUmtqeV formula: '[TRIP/End Station Id]' - id: T6FbNKHRi formula: '[TRIP/Bike Id]' - id: zFU89L0zlm formula: '[TRIP/Subscription Type]' - id: q9jRh6 formula: '[TRIP/Zip Code]' order: - MjRZA0G6v - bBxKd5WVwd9 - ExLXa3zphJn9 - pH9xdreYrmVM - 1JIJ5iqQt6 - wukvg6KLYr - vadWwbDVrE - OdUmtqeV - T6FbNKHRi - zFU89L0zlm - q9jRh6 - kind: control controlId: Row-Count id: nd1ItZ46uZudk filters: - source: kind: table elementId: 7AfSX columnId: t1qQzEeI controlType: top-n rankingFunction: rank mode: top-n rowCount: 10 includeNulls: when-no-value-is-selected - id: 7AfSX kind: bar-chart source: elementId: OetAfG8 kind: table columns: - id: ch_pH9xdreYrmVM formula: '[TRIP/Start Station Name]' - id: t1qQzEeI formula: Count() yAxis: columnIds: - t1qQzEeI xAxis: columnId: ch_pH9xdreYrmVM pages: - id: FLz0FoJA name: Page 1 kind: workbook layout: | documentVersion: 3 ``` ## Representing top N controls #### Top N control representation ```yaml ... kind: control controlId: Row-Count id: nd1ItZ46uZudk filters: - source: kind: table elementId: 7AfSX columnId: t1qQzEeI controlType: top-n rankingFunction: rank mode: top-n rowCount: 10 includeNulls: when-no-value-is-selected ... ``` ## Related resources * [Manage workbooks as code](/docs/manage-workbooks-as-code) * [Top N filter](/docs/top-n-filter)
