# Funnel, Sankey, and Waterfall Charts

> Set up Funnel, Funnel V2, Sankey, Waterfall, and Waterfall V2.

Funnel, Sankey, and Waterfall charts show stages, flows, and cumulative changes.

## Chart Types

| Chart            | Use case                                                 |
| ---------------- | -------------------------------------------------------- |
| **Funnel**       | Progression through stages (e.g., signup → trial → paid) |
| **Funnel V2**    | Updated funnel with D3 rendering                         |
| **Sankey**       | Flow between nodes (e.g., source → destination)          |
| **Waterfall**    | Cumulative effect of +/− changes (e.g., P\&L)            |
| **Waterfall V2** | Updated waterfall with enhanced styling                  |

## Funnel Setup

**Data:** One **step dimension** (stage order) + one **measure** (value per stage).

1. Add a dimension for stages and one measure.
2. Choose **Funnel** or **Funnel V2**.
3. Under **Required Axis**:
   * **Step**: The stage/category dimension.
   * **Measure**: The value per stage.

## Sankey Setup

**Data:** **Source** dimension + **Target** dimension + **Value** measure.

1. Add at least two dimensions (source, target) and one measure.
2. Choose **Sankey**.
3. Under **Required Axis**:
   * **Source**: "From" node column.
   * **Target**: "To" node column.
   * **Value**: Flow size (measure).

## Waterfall Setup

**Data:** One **category dimension** + one **measure**. Optional start value and total row.

1. Add a dimension (e.g., P\&L line items) and one measure.
2. Choose **Waterfall** or **Waterfall V2**.
3. Under **Required Axis**:
   * **Horizontal Axis**: Category dimension.
   * **Vertical Axis**: Measure (positive = up, negative = down).
4. In **Waterfall settings** (Appearance): configure increase/decrease colors, total styling, optional start value.
