iOS曲線圖：APLineChart

這是一個完全可定制曲線圖使用Interface Builder。

用法

What you have to do is to include APChartView directory in your project.

Than you have to use APChartView as Class used within Custom Class of the View that will use the Control. Next you have to link it to a class attribute, like you usually should do.

than you are free to customize it and to see the updates in realtime.

In order to add one or more line you have to simple follow these instructions:

// create a line
var line = APChartLine(chartView: chart, title: "prova", lineWidth: 2.0, lineColor: UIColor.purpleColor())

//add points to this line:
line.addPoint( CGPoint(x: 12.0, y: 24.0y))
line.addPoint( CGPoint(x: 16.0, y: 16.0y))
line.addPoint( CGPoint(x: 19.0, y: 20.0y))
line.addPoint( CGPoint(x: 21.0, y: 18.0y))

// and add the line to the chart:
chart.addLine(line)
