Highlight midPoint of visible area

https://stackoverflow.com/questions/56666001/swift-charts-highlight-center-point
I am trying to get the data point (highlight) closest to the middle of visible area of the graph.
I am, however, receiving the closest to the lower-left corner of visible area.
Details on stackoverflow.

Thanks in advance for any help.

EDIT:
I've figured out, that the valueForTouchPoint was performing a wrong transformation.
Disabling the .applying(pixelToValueMatrix) helped (I know I shouldn't comment it).

  @objc open func valueForTouchPoint(x: CGFloat, y: CGFloat) -> CGPoint
    {
        return CGPoint(x: x, y: y)//CGPoint(x: x, y: y).applying(pixelToValueMatrix)
    }

Fixed - I've been using the chart coordinates and not the UIViews coordinates.
