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 .
-
๐ Environment friendly. Support
iOSใiPadOSandmacOS. Totally supportSwiftlanguage, and there are more types version such asObjective-Clanguage version AAChartKit ใJavalanguage version AAChartCore ใKotlinlanguage version AAInfographics . To get more details you can see the source code links list. -
๐ 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 chartand other graphics. Support for more chart types is planned. -
๐ 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.
-
๐ฎ Interactive and animated. The charts
animationeffect is exquisite, delicate, smooth and beautiful. -
โ Chain programming. Supports
chain programming syntaxlike SwiftUI and Jetpack Compose. -
๐ฆ Minimalist.
AAChartView + AAChartModel = Chart. The AAInfographics follows a minimalist formula: Chart view + Chart model = The chart you want, just like the powerful and beautiful charts framework AAChartKit. -
๐ฑ 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.

- Download whole project demo of
AAInfographicsDemo - Drag the folder

- 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: 60,
width: chartViewWidth,
height: chartViewHeight)
// set the content height of aachartView
// aaChartView?.contentHeight = self.view.frame.size.height
self.view.addSubview(aaChartView!)- Configure the properties of chart model:
AAChartModel
let aaChartModel = AAChartModel()
.chartType(.area)//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()

.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]),

])- 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!)๐น๐น๐นCongratulations! 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!)
- Note: The following

you can monitor the user cick or finger move over events message through implementing delegate function for AAChartView instance object
//Set AAChartView events delegate
aaChartView!.delegate = self as AAChartViewDelegate
//implement AAChartView user click or finger move over events delegate function
extension BasicChartVC: AAChartViewDelegate {

public class AAClickEventMessageModel: AAEventMessageModel {}
public class AAMoveOverEventMessageModel: AAEventMessageModel {}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
As we all know, AAInfographics support using HTML String. Most of time, the headerFormat ใpointFormatใfooterFormat 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 ' ๐ ๐ ๐ ๐ ๐ ๐ ๐ ๐ <br/> '
+ ' Support JavaScript Function Just Right Now !!! <br/> '
