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 .

1. Support Android、Kotlin & Java.
2. Powerful,support the 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 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 AAChartKit、AAChartKit-Swift、AAChartCore.

Add it in your root build.gradle at the end of repositories:

	allprojects {
		repositories {
			...
			maven { url 'https://www.jitpack.io' }
		}
	}

	dependencies {
	        implementation 'com.github.AAChartModel:AAChartCore-Kotlin:-SNAPSHOT'
	}

You're all set, enjoy!

1. Create the instance object of chart view:AAChartView

    <com.github.aachartmodel.aainfographics.aachartcreator.AAChartView
        android:id="@+id/aa_chart_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </com.github.aachartmodel.aainfographics.aachartcreator.AAChartView>

    val aaChartView = findViewById<AAChartView>(R.id.aa_chart_view)

2. Configure the properties of chart model:AAChartModel

     val aaChartModel : AAChartModel = AAChartModel()
    .chartType(AAChartType.Area)
    .title("title")
    .subtitle("subtitle")
    .backgroundColor("#4b2b7f")
    .dataLabelsEnabled(true)
    .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))
    )
    )

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)

4. Finally add this line to your proguard file:

-keep class com.github.aachartmodel.aainfographics.** { *; }

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

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)

• line chart

• column chart

• bar chart

• special area chart one

• special area chart two

• special area chart three

• polar chart

• radar chart

• pie chart

• bubble chart

• scatter chart

• arearange chart

• step area chart

• mixed chart

• 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.

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
}

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:

   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👇
