Preface

AAInfographics is the Swift language version of AAChartKit which is object-oriented, a set of easy-to-use, extremely elegant graphics drawing controls,based on the popular open source front-end chart library Highcharts. It makes it very fast to add interactive charts to your mobile projects. It supports single touch-drag for data inspection, multi-touch for zooming, and advanced responsiveness for your apps .

Features

• 🎂 Environment friendly. Support iOS、iPadOS and macOS. Totally support Swift language, and there are more types version such as Objective-C language version AAChartKit 、 Java language version AAChartCore 、Kotlin language version AAInfographics . To get more details you can see the source code links list.

• 🚀 Powerful and easy to use. It supports column chart, bar chart, area chart, areaspline chart, line chart, spline chart, radar chart, polar chart, pie chart, bubble chart, pyramid chart, funnel chart, columnrange chart, arearange chart, mixed chart and other graphics. Support for more chart types is planned.

• 📝 Modern Declarative Syntax. Unlike previous imperative programming techniques, drawing any custom chart in AAChartKit, you don't need to care about the inner implementation details which is annoying && boring. Describe what you want, you will get what you described.

• 🎮 Interactive and animated. The charts animation effect is exquisite, delicate, smooth and beautiful.

• ⛓ Chain programming. Supports chain programming syntax like Masonry .

• 🦋 Minimalist. AAChartView + AAChartModel = Chart. The AAChartKit follows a minimalist formula: Chart view + Chart model = The chart you want, just like the powerful and beautiful charts framework AAChartKit.

• 🖱 Interaction event callback. Support for monitoring user click events and single finger move over events, which can be used to achieve double charts linked-working and even multiple charts linkage, as well as other more complex custom user interaction effects.

pod 'AAInfographics', :git => 'https://github.com/AAChartModel/AAChartKit-Swift.git'

to your project Podfile.

2. Run pod install or pod update.
3. Import AAInfographics.

Manually (old school way)

1. Download whole project demo of AAInfographicsDemo
2. Drag the folder AAInfographics into your project.

Usage

1. Creat the instance object of chart view:AAChartView

        let chartViewWidth  = self.view.frame.size.width
        let chartViewHeight = self.view.frame.size.height
        aaChartView = AAChartView()
        aaChartView?.frame = CGRect(x:0,y:0,width:chartViewWidth,height:chartViewHeight)
        // set the content height of aachartView
        // aaChartView?.contentHeight = self.view.frame.size.height
        self.view.addSubview(aaChartView!)

2. Configure the properties of chart model:AAChartModel

        let aaChartModel = AAChartModel()
            .chartType(.column)//Can be any of the chart types listed under `AAChartType`.
            .animationType(.bounce)
            .title("TITLE")//The chart title
            .subtitle("subtitle")//The chart subtitle
            .dataLabelsEnabled(false) //Enable or disable the data labels. Defaults to false
            .tooltipValueSuffix("USD")//the value suffix of the chart tooltip
            .categories(["Jan", "Feb", "Mar", "Apr", "May", "Jun",
                         "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"])
            .colorsTheme(["#fe117c","#ffc069","#06caf4","#7dffc0"])
            .series([
                AASeriesElement()
                    .name("Tokyo")
                    .data([7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]),
                AASeriesElement()
                    .name("New York")
                    .data([0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]),
                AASeriesElement()
                    .name("Berlin")
                    .data([0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]),
                AASeriesElement()
                    .name("London")
                    .data([3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]),
                    ])

3. Draw the chart(This method is called only for the first time after you create an AAChartView instance object)

        //The chart view object calls the instance object of AAChartModel and draws the final graphic
        aaChartView?.aa_drawChartWithChartModel(aaChartModel!)

🌹🌹🌹Congratulations! Everything was done!!! You will get what you want!!!

Update chart content

if you want to refresh chart content,you should do something as follow.According to your actual needs, select the function that fits you.

• Only refresh the chart data(This method is recommended to be called for updating the series data dynamically)

        //Only refresh the chart series data
        aaChartView?.aa_onlyRefreshTheChartDataWithChartModelSeries(chartModelSeriesArray)

• Refresh the chart, minus the chart data (this method is recommended for subsequent refreshes after the first drawing of graphics has completed. If you want to update the chart data only, you should use the function aa_onlyRefreshTheChartDataWithChartModelSeries)

        //Refresh the chart after the AAChartModel whole content is updated
        aaChartView?.aa_refreshChartWholeContentWithChartModel(aaChartModel!)

More graphics

• Note: The following DEMO picture is a GIF dynamic picture which has a size of around 6M. If you don't see any dynamic preview, then this is because the picture resources were not fully loaded. In such a case please be patient and wait for the contents to finish loading. Maybe you need to reload this page.

Special instructions

Support user click events and move over events

you can monitor the user touch events message through implementing delegate function for AAChartView instance object

 //Set AAChartView events delegate
 aaChartView!.delegate = self as AAChartViewDelegate
 //set AAChartModel support user touch event
 aaChartModel = aaChartModel!.touchEventEnabled(true)

 //implement AAChartView user touch events delegate function
extension CommonChartVC: AAChartViewDelegate {
   open func aaChartView(_ aaChartView: AAChartView, moveOverEventMessage: AAMoveOverEventMessageModel) {
       print("🔥selected point series element name: \(moveOverEventMessage.name ?? "")")
   }
}

The received touch events message contain following content

public class AAMoveOverEventMessageModel: NSObject {
    public var name: String?
    public var x: Float?
    public var y: Float?
    public var category: String?
    public var offset: [String: Any]?
    public var index: Int?
}

Monitoring user click events can achieve a variety of custom functions. For example, you can implement Double Charts Linkage through user click event callbacks. The example effects are as follows

Support for custom the style of chart AATooltip through JavaScript function

As we all know, AAInfographics support using HTML String. Most of time, the headerFormat 、pointFormat、footerFormat HTML string is enough for customizing chart tooltip string content, However, sometimes the needs of APP is so weird to satified, in this time, you can even customize the chart tooltip style through JavaScript function.

For example

• configuring AATooltip instance object properties as follow:

         aaOptions.tooltip?
            .useHTML(true)
            .formatter("""
function () {
        return ' 🌕 🌖 🌗 🌘 🌑 🌒 🌓 🌔 <br/> '
        + ' Support JavaScript Function Just Right Now !!! <br/> '
        + ' The Gold Price For <b>2020 '
        +  this.x
        + ' </b> Is <b> '
        +  this.y
        + ' </b> Dollars ';
        }
""")
            .valueDecimals(2)//设置取值精确到小数点后几位//设置取值精确到小数点后几位
            .backgroundColor("#000000")
            .borderColor("#000000")
            .style(AAStyle()
                .color("#FFD700")
                .fontSize(12)
        )

you can get the customized tooltip style chart like this👇

• configuring AATooltip instance object properties as follow:

        aaOptions.tooltip?
            .useHTML(true)
            .formatter(#"""
function () {
        let colorsArr = ["mediumspringgreen", "deepskyblue", "red", "sandybrown"];
        let wholeContentString ='<span style=\"' + 'color:lightGray; font-size:13px\"' + '>◉ Time: ' + this.x + ' year</span><br/>';
        for (let i = 0;i < 4;i++) {
            let thisPoint = this.points[i];
            let yValue = thisPoint.y;
            if (yValue != 0) {
                let spanStyleStartStr = '<span style=\"' + 'color:'+ colorsArr[i] + '; font-size:13px\"' + '>◉ ';
                let spanStyleEndStr = '</span> <br/>';
                wholeContentString += spanStyleStartStr + thisPoint.series.name + ': ' + thisPoint.y + '℃' + spanStyleEndStr;
            }
        }
        return wholeContentString;
    }
"""#)
            .backgroundColor("#050505")
            .borderColor("#050505")

you can get the customized tooltip style chart like this👇
