Как получить координаты мыши при масштабировании с помощью d3.js [duplicate]

Если вы хотите сделать это целиком из кода:

import UIKit

struct MatchInfo {
    var teamA: String
    var teamB: String
}

class ViewController: UIViewController, UITableViewDataSource {
    @IBOutlet weak var tableView: UITableView!

    var matches = [MatchInfo]()

    override func viewDidLoad() {
        super.viewDidLoad()
        self.tableView.dataSource = self

        // Add some data
        matches.append(MatchInfo(teamA: "Panthers", teamB: "Broncos"))
        matches.append(MatchInfo(teamA: "Bucaneers", teamB: "Falcons"))
        matches.append(MatchInfo(teamA: "Vikings", teamB: "Titans"))
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }


    // MARK: -
    // MARK: Table View Data Source Delegate
    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return matches.count
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("myCell") ?? makeCell()

        let textFieldA = cell.viewWithTag(1) as! UITextField
        let textFieldB = cell.viewWithTag(2) as! UITextField

        let row = indexPath.row
        textFieldA.text = matches[row].teamA
        textFieldB.text = matches[row].teamB

        return cell
    }

    func makeCell() -> UITableViewCell {
        let textFieldA = UITextField(frame: CGRectZero)
        let textfieldB = UITextField(frame: CGRectZero)

        textFieldA.tag = 1
        textfieldB.tag = 2
        [textFieldA, textfieldB].forEach {
            $0.translatesAutoresizingMaskIntoConstraints = false
            $0.borderStyle = .RoundedRect
        }

        let vsLabel = UILabel(frame: CGRectZero)
        vsLabel.text = "vs."
        vsLabel.translatesAutoresizingMaskIntoConstraints = false

        let cell = UITableViewCell(style: .Default, reuseIdentifier: "myCell")
        [textFieldA, textfieldB, vsLabel].forEach { cell.contentView.addSubview($0) }

        // Layout the elements
        let views = ["A": textFieldA, "B": textfieldB, "vs": vsLabel]
        let c1 = NSLayoutConstraint.constraintsWithVisualFormat("H:[A]-8-[vs]-8-[B]", options: .AlignAllBaseline, metrics: nil, views: views)
        let c2 = NSLayoutConstraint(item: textFieldA, attribute: .Left, relatedBy: .Equal, toItem: cell.layoutMarginsGuide, attribute: .Left, multiplier: 1, constant: 0)
        let c3 = NSLayoutConstraint(item: textfieldB, attribute: .Right, relatedBy: .Equal, toItem: cell, attribute: .Right, multiplier: 1, constant: 0)
        let c4 = NSLayoutConstraint(item: textFieldA, attribute: .CenterY, relatedBy: .Equal, toItem: cell.contentView, attribute: .CenterY, multiplier: 1, constant: 0)
        let c5 = NSLayoutConstraint(item: textFieldA, attribute: .Width, relatedBy: .Equal, toItem: textfieldB, attribute: .Width, multiplier: 1, constant: 0)

        NSLayoutConstraint.activateConstraints(c1 + [c2, c3, c4, c5])

        return cell
    }
}

Результат:
