# Change Series Color

After converting the chart to a **Column Stacked Chart**, you can further customize the visualization by **changing the color of an individual data series**.

In the Widget Dashboard configuration model, series‑level colors are controlled directly from the database table **`DASH_WIDGET_CHART_PROP`**.

***

#### Update Series Color Configuration

To change the color of a specific series (for example, **Bangkok**), update the **`FIELD_COLOR`** column in the **`DASH_WIDGET_CHART_PROP`** table for the corresponding series record.

Set the value as shown below:

```
FIELD_COLOR = 'green'
```

This configuration applies the specified color to the entire series during chart rendering.

***

#### Verify the Updated Chart

After updating the record:

1. Open the dashboard page again.
2. Click the **Training** menu (or the dashboard page you configured previously).

***

#### Expected Result

The chart is re‑rendered, and the **Bangkok** series now appears in **green**, as shown in the example below.

***

#### Summary

By updating the **`FIELD_COLOR`** column:

* You can visually differentiate individual series
* Improve chart readability and comparison clarity
* Apply consistent color mappings without modifying data logic

This completes the **series‑level styling configuration** for charts in the Widget Dashboard.
