## Usage

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

### Bar Graph

![Build Platform](images/bar-graph.png)

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

![Build Platform](images/line-graph.png)

```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].

#### `GKLineGraphDataSource` Protocol

```objc

@required

- (NSInteger)numberOfLines;

- (UIColor *)colorForLineAtIndex:(NSInteger)index;

- (NSArray *)valuesForLineAtIndex:(NSInteger)index;

@optional

- (CFTimeInterval)animationDurationForLineAtIndex:(NSInteger)index;

- (NSString *)titleForLineAtIndex:(NSInteger)index;

```
