Data Binding
You can bind the Pie series to an array that contains:
- Numbers.
- Arrays which represent
[value, category]tuples. - Objects which are also referred to as models.
When the Pie series is bound to objects (models), the user selects the relevant fields through the available bindings:
| Model binding | Data type | Required | Description |
|---|---|---|---|
field | number/null | Yes | The value of the data point, if any. |
categoryField | string/date/number/null | No | The category of the data point, if any. |
colorField | string | No | The color of the data point, if overridden. |
For more information on how to configure each data-binding mode, refer to the article on binding the Kendo UI Chart to data.
Auto-Fit Labels
To avoid the clipping of the labels content, use the autoFit series option.
