https://github.com/AAChartModel/AAChartCore-Kotlin

Preface

AAChartCore is the Java 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 all Android platforms. Totally support Java language, and there are more types version such as Kotlin language version AAInfographics、Swift language version AAChartKit-Swift 、 Objective-c language version AAChartKit . 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 concise chain programming syntax .

• 🦋 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 lib AAInfographics.

• 🖱 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.

Installation

JitPack (Recommend)

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

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

Usage

1. Creat the instance object of chart view:AAChartView

<com.github.AAChartModel.AAChartCore.AAChartCreator.AAChartView
android:id="@+id/AAChartView"android:layout_width="match_parent"android:layout_height="match_parent" />

aaChartView = findViewById(R.id.AAChartView)

2. Configure the properties of chart model:AAChartModel

AAChartModelaaChartModel = newAAChartModel()
.chartType(AAChartType.Area)
.title("THE HEAT OF PROGRAMMING LANGUAGE")
.subtitle("Virtual Data")
.backgroundColor("#4b2b7f")
.categories(newString[]{"Java", "Swift", "Python", "Ruby", "PHP", "Go", "C", "C#", "C++"})
.dataLabelsEnabled(false)
.yAxisGridLineWidth(0f)
.series(newAASeriesElement[]{
newAASeriesElement()
.name("Tokyo")
.data(newObject[]{7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6}),
newAASeriesElement()
.name("NewYork")
.data(newObject[]{0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5}),
newAASeriesElement()
.name("London")
.data(newObject[]{0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0}),
newAASeriesElement()
.name("Berlin")
.data(newObject[]{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 graphicaaChartView.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 dataaaChartView.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 updatedaaChartView.aa_refreshChartWholeContentWithChartModel(aaChartModel)

Infographics sample

• 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

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

publicinterfaceAAChartViewCallBack {
voidchartViewMoveOverEventMessage(AAChartViewaaChartView, AAMoveOverEventMessageModelmessageModel);
}

The received touch events message contain following content

publicclassAAMoveOverEventMessageModel {
publicStringname;
publicDoublex;
publicDoubley;
publicStringcategory;
publicLinkedTreeMapoffset;
publicDoubleindex;
}

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:

AATooltipaaTooltip = newAATooltip()
.useHTML(true)
.formatter(" function () {\n" +
" return ' 🌕 🌖 🌗 🌘 🌑 🌒 🌓 🌔 <br/> '\n" +
" + ' Support JavaScript Function Just Right Now !!! <br/> '\n" +
" + ' The Gold Price For <b>2020 '\n" +
" + this.x\n" +
" + ' </b> Is <b> '\n" +
" + this.y\n" +
" + ' </b> Dollars ';\n" +
" }")
.valueDecimals(2)
.backgroundColor("#000000")
.borderColor("#000000")
.style(newAAStyle()
.color("#FFD700")
.fontSize("12 px")
);

you can get the customized tooltip style chart like this👇
