An elegant and friendly chart library for Android developer who use Kotlin. Powerful,support the column chart、bar chart、area chart、area spline chart、line chart、spline chart、radar chart、polar chart、pie chart、bubble chart、pyramid chart、funnel chart、column range chart and other graphics.

Preface

AAInfographics is the Kotlin 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

  1. Support AndroidKotlin & Java.
  2. Powerful,support the column chartbar chartarea chartareaspline chartline chartspline chartradar chartpolar chartpie chartbubble chartpyramid chartfunnel chartcolumnrange chartand other graphics.
  3. Interactive、animated, the animation effect is exquisite 、delicate、 smooth and beautiful.
  4. Support chain programming syntax like system framework.
  5. AAChartView + AAChartModel = Chart In the AAInfographics,it follows a minimalist formula: Chart view + Chart model = The chart you want. Just like the other powerful charts framework AAChartKitAAChartKit-SwiftAAChartCore.

Appreciation

Installation

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
         <com.aachartmodel.aainfographics.aainfographicsLib.aachartConfiger.AAChartView
        android:id="@+id/AAChartView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
       aaChartView = findViewById(R.id.AAChartView)
  1. Configure the properties of chart model:AAChartModel
     val aaChartModel = AAChartModel()
    .chartType(AAChartType.Area)
    .title("title")
    .subtitle("subtitle")
    .backgroundColor("#4b2b7f")
    .dataLabelEnabled(true)
    .yAxisGridLineWidth(0)
    .legendVerticalAlign(AAChartLegendVerticalAlignType.Bottom)
    .series(arrayOf(
        AASeriesElement()
            .name("Tokyo")
            .data(arrayOf(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("NewYork")
            .data(arrayOf(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("London")
            .data(arrayOf(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("Berlin")
            .data(arrayOf(3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8))
    )
    )
  1. 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!)

AAChartKit-Live

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

   interface AAChartViewCallBack {
        fun chartViewMoveOverEventMessage(aaChartView: AAChartView, messageModel: AAMoveOverEventMessageModel)
    }

The received touch events message contain following content

class AAMoveOverEventMessageModel {
    var name: String? = null
    var x: Double? = null
    var y: Double? = null
    var category: String? = null
    var offset: LinkedTreeMap<*, *>? = null
    var index: Double? = null
}

Support for custom the style of chart AATooltip through JavaScript function

As we all know, AAInfographics support using HTML String. Most of time, the headerFormatpointFormatfooterFormat 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:

   val aaTooltip = AATooltip()
            .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 ';
        }
             """.trimIndent()
            )
            .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 px")
            )

you can get the customized tooltip style chart like this👇

Postscript

If you want to shrink the size of the AAInfographics lib ,you should do something like this:

  1. Delete the .js file of AAJSFiles folder in AAInfographics,The names of multiple files that need to be deleted are as follows
  • AAHighchartsLib.js
  • AAHighchartsMore.js
  • AAFunnel.js

2.Change the content of AAChartView.html file

<script src="AAHighchartsLib.js">
</script>
<script src="AAHighchartsMore.js">
</script>
<script src="AAFunnel.js">
</script>
