# Swift LineChart
## Usage
```swift
var lineChart = LineChart()
lineChart.addLine([3, 4, 9, 11, 13, 15])
```
## Features
- Super simple
- Highly customizable
- Auto scaling
- Touch enabled
- Area below lines
## Properties
Both `x` and `y` properties are of type `Coordinate`.
Each can be customized separately and has its own settings for labels, gridlines and axis.
- `labels`: Labels
- `grid`: Grid
- `axis`: Axis
`Labels` can be switched on and off and they can have custom values.
- `visible`: Bool = `true`
- `values`: [String] = `[]`
`Grid` can also be switched on/off, has a custom color and you can specify how many gridlines
you'd like to show.
- `visible`: Bool = `true`
- `count`: CGFloat = `10`
- `color`: UIColor = `UIColor(red: 238/255.0, green: 238/255.0, blue: 238/255.0, alpha: 1) // #eeeeee`
`Axis` can be switched on/off, has a property to its color and you can specify how much the axis
is inset from the border of your UIView.
- `visible`: Bool = `true`
- `color`: UIColor = `UIColor(red: 96/255.0, green: 125/255.0, blue: 139/255.0, alpha: 1) // 607d8b`
- `inset`: CGFloat = `15`
Animations can be customized through the `Animation` settings.
- `enabled`: Bool = `true`
- `duration`: CFTimeInterval = `1`
If you'd like to show extra dots at your data points use the `Dots` features.
- `visible`: Bool = `true`
- `color`: UIColor = `UIColor.whiteColor()`
- `innerRadius`: CGFloat = `8`
- `outerRadius`: CGFloat = `12`
- `innerRadiusHighlighted`: CGFloat = `8`
- `outerRadiusHighlighted`: CGFloat = `12`
In addition to the above mentioned features you can further customize your chart.
- `area`: Bool = `true` - Fill the area between line and x axis
- `lineWidth`: CGFloat = `2` - Set the line width
- `colors`: [UIColor] = `[...]` - Colors for your line charts
## Methods
Add line to chart.
`lineChart.addLine(data: [CGFloat])`
Remove charts, areas and labels but keep axis and grid.
`lineChart.clear()`
Make whole UIView white again
`lineChart.clearAll()`
## Delegates
`didSelectDataPoint()`
Touch event happened at or close to data point.
```swift
func didSelectDataPoint(x: CGFloat, yValues: [CGFloat]) {
println("\(x) and \(yValues)")
}
```
## Examples
#### Single line with default settings.
```swift
var lineChart = LineChart()
lineChart.addLine([3, 4, 9, 11, 13, 15])
```
#### Two lines without grid and dots.
```swift
var lineChart = LineChart()
lineChart.area = false
lineChart.x.grid.visible = false
lineChart.x.labels.visible = false
lineChart.y.grid.visible = false
lineChart.y.labels.visible = false
lineChart.dots.visible = false
lineChart.addLine([3, 4, 9, 11, 13, 15])
lineChart.addLine([5, 4, 3, 6, 6, 7])
```
#### Show x and y axis
```swift
var lineChart = LineChart()
lineChart.area = false
lineChart.x.grid.count = 5
lineChart.y.grid.count = 5
lineChart.addLine([3, 4, 9, 11, 13, 15])
lineChart.addLine([5, 4, 3, 6, 6, 7])
```
