# HypothesisInstances

> Instances of a Repeating Group element in the FlexiLayout language, with hypothesis methods plus GetYArray to retrieve Y coordinates of instance rectangles.

Describes instances of a Repeating Group element. Has the same methods as hypotheses. For more information on the methods of hypotheses, see [Hypotheses for all types of element](/vantage/documentation/advanced-designer/activities/flexilayout/hypotheses/hypothesis-for-all).

## Methods

| Method                                     | Description                                                                                                                                                                 |

| `YCoordinateArray GetYArray( Real ratio )` | Returns the array of Y coordinates of instance rectangles. To calculate the Y coordinate, the following formula is used: Top + Height \* ratio. Null instances are ignored. |
