# 9.4 - Scenarios in tree layout
This article explains how to create and work with scenarios in tree layout.
1. Create a matrix and, on the **Planning** tab, select **Tree** from the **Layout** dropdown.
2. Configure the baseline measure.
3. Select the comparison measure and select **Save**.
4. On the **Tree View** ribbon, select **Create scenario**.
5. Enter a name for the scenario. Select the series to include in the scenario. Select **Create**.
6. Use the Scenario menu to navigate between scenarios or create new ones.
### Simulate scenario values
1. Hover over a tile to display the simulation slider and adjust values. Simulated values are automatically distributed to descendant nodes.
2. Simulated values automatically roll up to higher levels in the hierarchy.
3. Review sparklines and accent lines, which are color-coded based on variance.
4. To prevent values from being simulated, hover over a tile, select the ellipsis (**⋮**) menu, and then select **Simulation lock**.
5. Simulated values appear at the top of the canvas.
### Further customization
1. Select the arrow on a tile to collapse or expand descendant nodes.
2. Select the ellipsis (**⋮**) menu to access actions such as pinning, editing, commenting, and locking values.
3. Select **Simulate per Period** to adjust simulation values across time periods.
4. Enter precise values for each period to simulate the values for the selected node.
5. Select **View Details** to access additional insights.
6. On the **Trends** tab, compare values over time across scenarios and measures.
7. Select **Table** to switch to a tabular view of the data.
8. Select **Details** to view information about the selected node, including value, simulation impact, and variance.
9. Select **Variance** to compare the variance between the primary and comparison values for the selected total and its descendants.
10. Select **Simulation** to visualize the impact of simulated values on the base measure.
11. Select **Dependents** to view trends over time for dependent nodes.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.fabricplan.com/user-guide/9-scenario-planning/9-4-scenarios-in-tree-layout.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
