To see a quick demo, simply type `pod try GraphKit`.
### Bar Graph

Initialize `GKBarGraph` from nib or programmatically:
```objc
CGRect frame = CGRectMake(0, 40, 320, 200);
self.graphView = [[GKBarGraph alloc] initWithFrame:frame];
```then set `GKGraphViewDataSource`
```objc
self.graphView.dataSource = self;
```and call `draw` method.
```objc
[self.graphView draw];
```Please see [example][BAR].

#### `GKBarGraphDataSource` Protocol
```objc
@required
- (NSInteger)numberOfBars;
- (NSNumber *)valueForBarAtIndex:(NSInteger)index;@optional
- (UIColor *)colorForBarAtIndex:(NSInteger)index;
- (UIColor *)colorForBarBackgroundAtIndex:(NSInteger)index;
- (CFTimeInterval)animationDurationForBarAtIndex:(NSInteger)index;
- (NSString *)titleForBarAtIndex:(NSInteger)index;
```### Line Graph

```objc
CGRect frame = CGRectMake(0, 40, 320, 200);
self.graphView = [[GKLineGraph alloc] initWithFrame:frame];self.graph.dataSource = self;
self.graph.lineWidth = 3.0;[self.graph draw];
```Please see [example][LINE].

- (NSInteger)numberOfLines;
- (UIColor *)colorForLineAtIndex:(NSInteger)index;
- (NSArray *)valuesForLineAtIndex:(NSInteger)index;@optional
- (CFTimeInterval)animationDurationForLineAtIndex:(NSInteger)index;
