# Combo Chart (Bar + Line)

> Set up Combo, Horizontal Combo, and Vertical Combo charts with bar and line series.

Combo charts mix **bars** and **lines** so you can show measures with different scales (e.g., revenue and growth rate).

## Chart Types

| Chart                | Orientation                       |
| -------------------- | --------------------------------- |
| **Combo**            | Vertical bars + line; dual Y-axes |
| **Horizontal Combo** | Horizontal bars + line            |
| **Vertical Combo**   | Vertical bars; stacked or grouped |

## Data Requirements

* One **dimension** (X-axis categories)
* Two or more **measures** (for bars and/or lines)

## How to Set Up

1. Create or edit a metric with one dimension and two or more measures.
2. Click the **Charts** icon and choose **Combo**, **Horizontal Combo**, or **Vertical Combo**.
3. Click **Settings** → **Chart types** → **Chart properties**.
4. Under **Required Axis**:
   * **Horizontal Axis**: Dimension for categories.
   * **Vertical Axis**: Select the measures to show.
   * **Combo Bar**: Choose which measure(s) are shown as **bars**; the rest appear as **lines**.

## Axis and Series

In **Appearance & Actions** → **Combo chart settings** (or chart configuration):

* Assign each measure to **Left** or **Right** Y-axis.
* Set each measure as **Bar** or **Line**.
* Set **Prefix** and **Suffix** per axis (e.g., "\$", "%").

## Group X-Axis

When you have multiple dimensions, **Group X-Axis** aggregates categories. Enable it in **Actions** to consolidate the X-axis.
