Preface

AAChartKit is an elegant and friendly (user-friendly && enviroment-friendly) chart framework for iOS, based on the open source Highcharts JS libraries. AAChartKit is extremely powerful, easy to configure and a pleasure to use. Currently AAChartKit includes support for the following chart types: 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 and area range chart. More chart types are planned to be supported. AAChartKit gives you easy and fast access to a wide range of chart types, hassle-free and quick to integrate into your own project.

Features

  • 🎂 Environment friendly. Support iOS 、 iPadOS、tvOS and macOS. Totally support Objective-C language, and there are more types version such as Swift language version AAInfographics 、 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 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

CocoaPods (recommend)

  1. Add following content
pod 'AAChartKit', :git => 'https://github.com/AAChartModel/AAChartKit.git'

to your Podfile.

  1. Run pod install or pod update.

Manually (old school way)

  1. Drag the AAChartKitLib folder into your project.

  2. Add the following to your .pch file.

#import "AAGlobalMacro.h"

Usage

  1. Add the following to your view controller file:
#import "AAChartKit.h"
  1. Create an instance object of chart view:AAChartView
CGFloat chartViewWidth  = self.view.frame.size.width;
CGFloat chartViewHeight = self.view.frame.size.height-250;
_aaChartView = [[AAChartView alloc]init];
_aaChartView.frame = CGRectMake(0, 60, chartViewWidth, chartViewHeight);
//_aaChartView.scrollEnabled = NO;
//// set the content height of aaChartView
// _aaChartView.contentHeight = chartViewHeight;
[self.view addSubview:_aaChartView];
  1. Configure the chart model properties: AAChartModel
AAChartModel *aaChartModel= AAObject(AAChartModel)
.chartTypeSet(AAChartTypeArea)
.titleSet(@"THE HEAT OF PROGRAMMING LANGUAGE")
.subtitleSet(@"Virtual Data")
.categoriesSet(@[@"Java",@"Swift",@"Python",@"Ruby", @"PHP",@"Go",@"C",@"C#",@"C++"])
.yAxisTitleSet(@"Degrees Celsius")
.seriesSet(@[
        AAObject(AASeriesElement)
        .nameSet(@"2017")
        .dataSet(@[@7.0, @6.9, @9.5, @14.5, @18.2, @21.5, @25.2, @26.5, @23.3, @18.3, @13.9, @9.6]),
        AAObject(AASeriesElement)
        .nameSet(@"2018")
        .dataSet(@[@0.2, @0.8, @5.7, @11.3, @17.0, @22.0, @24.8, @24.1, @20.1, @14.1, @8.6, @2.5]),
        AAObject(AASeriesElement)
        .nameSet(@"2019")
        .dataSet(@[@0.9, @0.6, @3.5, @8.4, @13.5, @17.0, @18.6, @17.9, @14.3, @9.0, @3.9, @1.0]),
        AAObject(AASeriesElement)
        .nameSet(@"2020")
        .dataSet(@[@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 only called the first time 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.

  • Refresh the chart data (this method is recommended for updating the series data dynamically)
//Refresh the chart dynamically only when the series attribute of the AAChartModel object is updated
[_aaChartView aa_onlyRefreshTheChartDataWithChartModelSeries:aaChartModelSeriesArray];
  • 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 content is updated
[_aaChartView aa_refreshChartWithChartModel:aaChartModel];

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
 self.aaChartView.delegate = self;
 
 //set AAChartModel support user touch event
 self.aaChartModel.touchEventEnabledSet(true)

 //implement AAChartView user touch events delegate function
 #pragma mark -- AAChartView delegate
 - (void)aaChartView:(AAChartView *)aaChartView moveOverEventWithMessage:(AAMoveOverEventMessageModel *)message {
 NSLog(@"🚀selected point series element name: %@",message.name);
 }

The received touch events message contain following content

@interface AAMoveOverEventMessageModel : NSObject

@property (nonatomic, copy)   NSString *name; 
@property (nonatomic, strong) NSNumber *x; 
@property (nonatomic, strong) NSNumber *y;
@property (nonatomic, copy)   NSString *category;
@property (nonatomic, strong) NSDictionary *offset;
@property (nonatomic, assign) NSUInteger index;

@end

Support for custom the style of chart AATooltip through JavaScript function

As we all know, AAChartKit 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 via formatter JavaScript function.

For example

  • configuring AATooltip instance object properties as follow:
 /*Custom Tooltip Style ---*/
    AATooltip *tooltip = aaOptions.tooltip;
    tooltip
    .useHTMLSet(true)
    .formatterSet(@AAJSFunc(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 ';
    }))
    .valueDecimalsSet(@2)
    .backgroundColorSet(@"#000000")
    .borderColorSet(@"#000000")
    .styleSet((id)AAStyle.new
              .colorSet(@"#FFD700")
              .fontSizeSet(@"12px"))
    ;

you can get the customized tooltip style chart like this👇

  • configuring AATooltip instance object properties as follow:
 aaOptions.tooltip
 .useHTMLSet(true)
 .formatterSet(@AAJSFunc(function () {
     let colorsArr = [];
     colorsArr.push("mediumspringgreen");
     colorsArr.push("deepskyblue");
     colorsArr.push("red");
     colorsArr.push("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;
 }))
 .backgroundColorSet(@"#050505")
 .borderColorSet(@"#050505")
 ;

you can get the customized tooltip style chart like this👇
