# Bi-Variate Area
A **BiVariate Area Chart** is a multi-panel (small multiples) visualization combining area charts with grid layouts split by a **Split** dimension and optionally grouped by a **Group** dimension. Each grid represents a distinct subset of data while maintaining consistent axes for easy comparison.
It supports both **Horizontal** (standard area chart with X-axis as categories) and **Vertical** (area flows along Y-axis categories) orientations.
**Key Features:**
- **Multi-grid (small multiples)** area charts split by a **Split** dimension.
- Optional **Group dimension** for multiple filled area plots in each grid.
- Toggle between **Horizontal** and **Vertical** orientation.
- Custom area colors, opacity, line styles, and point markers.
- Interactive zoom and tooltip support for every panel.
- Heatmap coloring based on value ranges.
- Supports sorting, legends, and pivot-based group breakdown.
**Use Cases:**
- Sales or revenue area comparisons across regions.
- Customer count or activity growth per product category.
- System performance metrics split by device type or region.
- Sensor trends split by equipment and grouped by status type.

## ⚙️ Setup
1. Add the **BiVariate Area Chart** widget from the chart library onto your designer workspace.
2. Select the chart.
3. Go to the [Widget Configuration](/insights-v8/guide-to-infoboard-designer/customize-panel/configure/) tab in the Customize panel.
4. Under the Configuration tab, select the [Basic Configuration](/insights-v8/guide-to-infoboard-designer/customize-panel/configure/#basic) option to access the essential settings for the bi variate area chart.
5. Select the [Source](/insights-v8/guide-to-infoboard-designer/customize-panel/setup/#sources) which the chart will pull the data from the option.
6. Map:
- **[Value (Measure)](/studio-v8/datasources/measures-dimensions-and-hierarchies/)** — The numeric value plotted along the Y-axis (or X if vertical).
- **[Axis (Dimension)](/studio-v8/datasources/measures-dimensions-and-hierarchies/)** — The categorical or date/time value for the independent axis.
- **[Split (Dimension)](/studio-v8/datasources/measures-dimensions-and-hierarchies/)** — The dimension used to split charts into grids.
- (Optional) **[Group (Dimension)](/studio-v8/datasources/measures-dimensions-and-hierarchies/)** — Categorizes multiple lines within a panel.
7. Optionally add a **Date** field for time-based filtering.
8. Enable **Hide Zero Values** to omit symbols with zero values if needed.
