## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_quicksight as quicksight } from 'aws-cdk-lib';
const aggregationFunctionProperty: quicksight.CfnDashboard.AggregationFunctionProperty = {
  attributeAggregationFunction: {
    simpleAttributeAggregation: 'simpleAttributeAggregation',
    valueForMultipleValues: 'valueForMultipleValues',
  },
  categoricalAggregationFunction: 'categoricalAggregationFunction',
  dateAggregationFunction: 'dateAggregationFunction',
  numericalAggregationFunction: {
    percentileAggregation: {
      percentileValue: 123,
    },
    simpleNumericalAggregation: 'simpleNumericalAggregation',
  },
};
```
