已经用:

[记录]使用Cocoapods管理iOS项目的第三方库

安装好了Charts的库,现在尝试在iOS中用swift去使用

Charts/ChartsDemo at master · danielgindi/Charts

PhilJay/MPAndroidChart: A powerful Android chart view / graph view library, supporting line- bar- pie- radar- bubble- and candlestick charts as well as scaling, dragging and animations.

文档:

Home · PhilJay/MPAndroidChart Wiki

API:

Overview (MPChartLib v2.2.4 API)

去下载:

https://github.com/danielgindi/Charts/archive/master.zip

找demo看看

[已解决]Xcode中可以编译但是无法运行iOS项目

虽然搞懂了原因,但是没有搞定如何继续运行demo项目。

没法看效果。

只能看oc的代码。。。

swift charts library demo

Looking for Swift tutorial on iOS Charts:swift

iOS Swift Tutorial: Fitness tracking and iOS charts

How To Draw Graphs with Core Plot, Part 1

然后参考这个:

How to Use iOS Charts API to Create Beautiful Charts in Swift

最后用如下代码:

        super.init(nibName: nil, bundle: nil)

    }

        //init data

//        let months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]

//        let unitsSold = [20.0, 4.0, 6.0, 3.0, 12.0, 16.0, 4.0, 18.0, 2.0, 4.0, 5.0, 4.0]

        let months = ["一月", "二月", "三月", "四月", "五月", "六月"]

        let unitsSold = [20.0, 4.0, 6.0, 3.0, 12.0, 16.0]

       

        //set values

        setChart(months, values: unitsSold)

    }

   

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

    }

   

    func setChart(dataPoints: [String], values: [Double]) {

        var dataEntries: [BarChartDataEntry] = []

       

        for i in 0..<dataPoints.count {

            let dataEntry = BarChartDataEntry(value: values[i], xIndex: i)

            dataEntries.append(dataEntry)

        }

        let chartDataSet = BarChartDataSet(yVals: dataEntries, label: "销量")

        let chartData = BarChartData(xVals: dataPoints, dataSet: chartDataSet)

        print("chartData=\(chartData)")

        barChartView.data = chartData

    }

   

}

效果如图所示:

双击(鼠标)后,可以放大:

然后再去试试,线line的图表:

效果:

然后再去弄,X的双轴的线line的图表,代码:

最后集成了4个:

x带双轴的线line图表

x单轴的的线line图表

柱状图bar
