# `GSLayer coordinateForAxisId:`

*Instance Method*

Returns an explicit Intermediate-layer coordinate, or `NSNotFound` when no coordinate is set for the axis.

## Declaration

```swift
func coordinate(forAxisId axisId: String) -> CGFloat
```

```objc
- (CGFloat) coordinateForAxisId:(NSString *) axisId;
```

```python
coordinateForAxisId_(axisId: str) -> float
```

## Parameters

- `axisId` — The axis identifier.
