Usage:

Import header file

#import "JEBarChart.h"
#import "JESimplePieChart.h"
#import "JECurvedPlotView.h"
#import "JEControlChart.h"

JEControlChart.

Objective-C
- (void)testControlChart {

    JEControlChart *plotItem = [[JEControlChart alloc]init];
    NSMutableArray *contentArray = [NSMutableArray array];
    
    int count = 31;
    for ( int j = 0; j < count+1; j++ ) {
        [contentArray addObject:@(0)];
    }
    
    plotItem.plotData = contentArray;
    plotItem.numberOfPoints = 31;
    
    plotItem.plotData1 = contentArray;
    plotItem.numberOfPoints = 31;
    
    UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 100, 320, 150)];
    [self.view addSubview:view];
    
    self.pieChartDetailItem = plotItem;
    [self.pieChartDetailItem renderInView:view withTheme:nil animated:YES];
}

JESimplePie Chart

Objective-C
- (void)testSimplePiechart {
    PlotItem *plotItem = [[JESimplePieChart alloc]init];
    UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 400)];
    [self.view addSubview:view];
    
    ((JESimplePieChart*)plotItem).plotData = @[@20.0, @30.0, @60.0];
    
    self.pieChartDetailItem = plotItem;
    [self.pieChartDetailItem renderInView:view withTheme:nil animated:YES];
}

JEBarChart

Objective-C
- (void)testBarChart {
    PlotItem *plotItem  = [[JEBarChart alloc]init];
    UIView *barView = [[UIView alloc]initWithFrame:CGRectMake(0, 200, 320, 200)];
    [self.view addSubview:barView];
    [_barChartDetailItem renderInView:barView withTheme:[CPTTheme themeNamed:kCPTPlainWhiteTheme] animated:YES];

    self.pieChartDetailItem = plotItem;
    [self.pieChartDetailItem renderInView:barView withTheme:nil animated:YES];
