## How to use

You can add view in the Interface Builder and set a class to Chart or create in the code: 



Chart *chart = [[Chart alloc] initWithFrame:CGRectMake(0, 256, 256, 256)];

[self.view addSubview:chart];



For adding chart data, you can use the following code: 



NSMutableArray *array = [[NSMutableArray alloc] init];

    

float total;

for (NSInteger groupIndex = 0; groupIndex < 5; ++groupIndex) {

  [array removeAllObjects];

  total = 0.0;

  for (NSInteger itemIndex = 0; itemIndex < 10; ++itemIndex) {

    ChartItem *item = [[ChartItem alloc] init];

    item.name = [NSString stringWithFormat:@"Item %d", itemIndex];

    item.value = RAND_FROM_TO(1, 500);

    total += item.value;

    [array addObject:item];

  }

  [self.chart setData:array withKey:[NSString stringWithFormat:@"Group %d", groupIndex+1] withTotal:total];

}



For scrolling datasets just tap on the chart.




If you have one set of data, and you won't scroll them, use the following property:


@property BOOL isScrollEnabled;
