Complete Guide for Pie Chart and Fragmented Pie Chart (MIM Chart Lib)

So our data looks like following and we will make pie chart of the Income column.

Code is in XCode proj > HowToUseFiles> TestClass.m

     [MIMColor InitColors];

    NSString *csvPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"myTable.csv"];

    MIMPieChart *pieChartView=[[MIMPieChart alloc]initWithFrame:CGRectMake(40, 40, 600, 500)];

    pieChartView.radius=200;

    pieChartView.tint=BEIGETINT;// Available Tints: GREENTINT,REDTINT,BEIGETINT

    [pieChartView readFromCSV:csvPath  TitleAtColumn:0  DataAtColumn:4];

    [pieChartView drawPieChart];

    [self.view addSubview:pieChartView];

It will make the pie chart look like following, you can change the tint color to see what they look like OR you can GO TO THIS POST to see them. If you tap on a region of pie chart, the respective information label gets highlighted, as in this case Indonesia is highlighted.

Now lets look at fragmented piechart , for now we can give data only through arrays, I need to add support for csv format. But you can use it as following as in XCode proj > HowToUseFiles> TestClassFragmented.m

      [MIMColor InitColors];

    

    _DFragmentedDoughNut *detailedDoughNut=[[_DFragmentedDoughNut alloc]initWithFrame:CGRectMake(0, 0, 600, 600)];

    detailedDoughNut.tint=GREENTINT;// Available Tints: GREENTINT,REDTINT,BEIGETINT

    detailedDoughNut.isShadow=YES;

    [detailedDoughNut setValuesArray:[NSArray arrayWithObjects:@"23",@"45",@"89",@"123",@"21",@"144", nil]];

    [detailedDoughNut setTitleArray:[NSArray arrayWithObjects:@"U.P.",@"Bihar",@"Delhi",@"Punjab",@"Haryana",@"Rajasthan", nil]];

    [detailedDoughNut setOutRadius:200 AndInnerRadius:300];

    [self.view addSubview:detailedDoughNut];

    

Output looks like following
