Multiline chart, now with less code

I started adding some convenience classes to SwiftCharts to create popular charts quickly.

This is how now a multiline chart is created:

let chart = LineChart(
    frame: CGRectMake(0, 70, 300, 500),
    chartConfig: ChartConfig(
        xAxisConfig: ChartAxisConfig(from: 2, to: 14, by: 2),
        yAxisConfig: ChartAxisConfig(from: 0, to: 14, by: 2)
    ),
    xTitle: "X axis",
    yTitle: "Y axis",
    lines: [
        (chartPoints: [(2.0, 10.6), (4.2, 5.1), (7.3, 3.0), (8.1, 5.5), (14.0, 8.0)], color: UIColor.redColor()),
        (chartPoints: [(2.0, 2.6), (4.2, 4.1), (7.3, 1.0), (8.1, 11.5), (14.0, 3.0)], color: UIColor.blueColor())
    ]
)
self.view.addSubview(chart.view)

Of course the "low level" api and examples continue to be available, and should be used when the convenience charts don't provide the required level of customization.

More will follow!
