Your graphing view must be @IBDesignable and its scale must be @IBInspectable. The graphing view’s axes should appear in the storyboard at the inspected scale.

Add the respective keywords in the lines above the class and the property definitions:

@IBDesignable
class GraphView: UIView {
...
    @IBInspectable
    var scale: CGFloat = 50.0 { didSet { setNeedsDisplay() } }

… and you should see the axis in storyboard, and when inspecting the graph view see the new property scale:
