This documentation describes one or more public beta features that are in development. Beta features are subject to quick, iterative changes; therefore the current user experience in the Sigma service can differ from the information provided in this page. This page should not be considered official published documentation until Sigma removes this notice and the beta flag on the corresponding feature(s) in the Sigma service. For the full beta feature disclaimer, see [Beta features](/docs/sigma-product-releases#beta-features). 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 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 box chart that compares the distribution of average trip duration across subscription types, split by start station. 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. Select ![](https://sigma-docs-screenshots.s3.us-west-2.amazonaws.com/Icons/add-dependent.svg) **Add child element** > **Chart**. A new bar chart element appears on the workbook canvas. 7. In the editor panel, select **Properties** and in the **Chart** dropdown, select **Box**. 8. Configure the box chart with the following settings: | Option | Setting | | :----------- | :------------------- | | **X-axis** | *Subscription Type* | | **Y-axis** | *Duration* | | **Split by** | *Start Station Name* | 9. For the **Y-axis** column, select the down arrow ![](https://sigma-docs-screenshots.s3.us-west-2.amazonaws.com/Icons/caret.svg) to open the column menu, then select **Set aggregate** > **Average**. The Y-axis column becomes `Avg([Duration])`. A box chart summarizes a distribution, so aggregating the value column is what gives each box its spread. 10. In the document header, select **Save as**. 11. Enter a name for the workbook, such as `box-chart`. 12. 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: 6066323d-6873-496b-bf14-a0ed13132118 workbookUrlId: igIeGy6CnVCTK6ujvYhYxD createdBy: zgzXpTRVbfX4ZE9TEm9q9fUsfXZ5o updatedBy: zgzXpTRVbfX4ZE9TEm9q9fUsfXZ5o createdAt: '2026-08-13T23:39:08.742Z' updatedAt: '2026-09-02T15:26:56.873Z' name: box-chart url: https://aws-api.sigmacomputing.com/org-name/workbook/igIeGy6CnVCTK6ujvYhYxD path: My Documents/ latestVersion: 3 ownerId: zgzXpTRVbfX4ZE9TEm9q9fUsfXZ5o isArchived: false contents: schemaVersion: 1 elements: - id: eTizXgX kind: table source: connectionId: b2af3691-12a0-48fa-a91d-fbe2e1b31627 kind: warehouse-table path: - EXAMPLES - BIKES - TRIP columns: - id: 6DqBgE6Rq formula: '[TRIP/Id]' - id: wOW6NNWOZqI formula: '[TRIP/Duration]' - id: jC0c8h8Ewz3g formula: '[TRIP/Start Date]' - id: cOIGflvCqIlC formula: '[TRIP/Start Station Name]' - id: JpVJowwqZg formula: '[TRIP/Start Station Id]' - id: GyZynaXgfv formula: '[TRIP/End Date]' - id: qQzuJifMd2 formula: '[TRIP/End Station Name]' - id: 3Esuzz9y formula: '[TRIP/End Station Id]' - id: a1ySXDMEm formula: '[TRIP/Bike Id]' - id: Kng0H6Uvst formula: '[TRIP/Subscription Type]' - id: B0QtJd formula: '[TRIP/Zip Code]' order: - 6DqBgE6Rq - wOW6NNWOZqI - jC0c8h8Ewz3g - cOIGflvCqIlC - JpVJowwqZg - GyZynaXgfv - qQzuJifMd2 - 3Esuzz9y - a1ySXDMEm - Kng0H6Uvst - B0QtJd - id: F4gqP kind: box-chart source: elementId: eTizXgX kind: table columns: - id: ch_Kng0H6Uvst formula: '[TRIP/Subscription Type]' - id: ch_cOIGflvCqIlC formula: '[TRIP/Start Station Name]' - id: 8vk0TaP1pa-ch_wOW6NNWOZqI formula: Avg([Duration]) - id: ch_wOW6NNWOZqI formula: '[TRIP/Duration]' - id: ch_6DqBgE6Rq formula: '[TRIP/Id]' - id: ch_jC0c8h8Ewz3g formula: '[TRIP/Start Date]' - id: ch_JpVJowwqZg formula: '[TRIP/Start Station Id]' - id: ch_GyZynaXgfv formula: '[TRIP/End Date]' - id: ch_qQzuJifMd2 formula: '[TRIP/End Station Name]' - id: ch_3Esuzz9y formula: '[TRIP/End Station Id]' - id: ch_a1ySXDMEm formula: '[TRIP/Bike Id]' - id: ch_B0QtJd formula: '[TRIP/Zip Code]' yAxis: columnIds: - 8vk0TaP1pa-ch_wOW6NNWOZqI xAxis: columnId: ch_Kng0H6Uvst splitBy: columnId: ch_cOIGflvCqIlC pages: - id: eKhTktnw name: Page 1 kind: workbook layout: | documentVersion: 3 ``` ## Representing box charts #### Box chart representation ```yaml ... id: F4gqP kind: box-chart source: elementId: eTizXgX kind: table columns: - id: ch_Kng0H6Uvst formula: '[TRIP/Subscription Type]' - id: ch_cOIGflvCqIlC formula: '[TRIP/Start Station Name]' - id: 8vk0TaP1pa-ch_wOW6NNWOZqI formula: Avg([Duration]) - id: ch_wOW6NNWOZqI formula: '[TRIP/Duration]' - id: ch_6DqBgE6Rq formula: '[TRIP/Id]' - id: ch_jC0c8h8Ewz3g formula: '[TRIP/Start Date]' - id: ch_JpVJowwqZg formula: '[TRIP/Start Station Id]' - id: ch_GyZynaXgfv formula: '[TRIP/End Date]' - id: ch_qQzuJifMd2 formula: '[TRIP/End Station Name]' - id: ch_3Esuzz9y formula: '[TRIP/End Station Id]' - id: ch_a1ySXDMEm formula: '[TRIP/Bike Id]' - id: ch_B0QtJd formula: '[TRIP/Zip Code]' yAxis: columnIds: - 8vk0TaP1pa-ch_wOW6NNWOZqI xAxis: columnId: ch_Kng0H6Uvst splitBy: columnId: ch_cOIGflvCqIlC ... ```
