# Donut Series

This series becomes active when a donut series is selected for a measure in the Y-axis.

## Key Properties

The following properties can be set for a donut series

### Radius

In a donut chart, **inner radius** and **outer radius** are used to define the size and thickness of the donut ring:

* **Inner Radius**: This determines the size of the hole in the center of the donut. A smaller inner radius results in a smaller hole, while a larger inner radius increases the hole, making the ring thinner.
* **Outer Radius**: This controls the outer edge of the donut. A larger outer radius will make the donut chart bigger, and a smaller one will shrink the chart.

### 3D Chart

Add a three-dimensional effect to data, making it appear as though the chart has depth and perspective.

### Border

This property can be used to control the outline or border of the pie and its style and color. 

* **Width** - Higher the value thicker is the outline or border.
* **Style** - Outline can be solid, dashed or dotted.
* **Color** - Specifies the color of the outline.

{% hint style="info" %}
***A size of 0 or a style set to "None" will remove the outline.***
{% endhint %}
