#NKWatchChart#
A chart library for Apple Watch based on [PNChart](https://github.com/kevinzhow/PNChart). We support line, bar, pie, circle and radar charts now and will integrate more chart types from [ios-charts](https://github.com/danielgindi/ios-charts).
##Usage##
###Cocoapods###
In your watchOS target
pod 'NKWatchChart'
Then
pod install
And
#import "NKWatchChart.h"
[Using Cocoapods with watchOS 2](https://medium.com/@JTEhlert/using-cocoapods-with-watchos-2-723b92eae04f) by Justin Ehlert
###Copy NKWatchChart folder to watch app extension ###
##Requirements##
* watchOS ~> 2.0
* Xcode >= 7.0
##Examples##
####Line Chart####
```objective-c
NKLineChart *chart = [[NKLineChart alloc] initWithFrame:frame];
chart.yLabelFormat = @"%1.1f";
[chart setXLabels:@[@"SEP 1",@"SEP 2",@"SEP 3",@"SEP 4",@"SEP 5",@"SEP 6",@"SEP 7"]];
chart.showCoordinateAxis = YES;
//Use yFixedValueMax and yFixedValueMin to Fix the Max and Min Y Value
//Only if you needed
chart.yFixedValueMax = 300.0;
chart.yFixedValueMin = 0.0;
[chart setYLabels:@[
@"0",
@"50",
@"100",
@"150",
@"200",
@"250",
@"300",
]
];
chart.yLabelFont = [UIFont systemFontOfSize:6.f];
chart.xLabelFont = [UIFont systemFontOfSize:6.f];
chart.xLabelWidth = 10.f;
chart.yLabelColor = NKGreen;
chart.xLabelColor = NKGreen;
chart.axisColor = NKLightGrey;
chart.axisWidth = 1.f;
chart.xUnit = @"Day";
chart.yUnit = @"Min";
// Line Chart #1
NSArray * data01Array = @[@60.1, @160.1, @126.4, @0.0, @186.2, @127.2, @176.2];
NKLineChartData *data01 = [NKLineChartData new];
data01.color = NKGreen;
data01.alpha = 0.9f;
data01.itemCount = data01Array.count;
data01.inflexionPointStyle = NKLineChartPointStyleTriangle;
data01.getData = ^(NSUInteger index) {
CGFloat yValue = [data01Array[index] floatValue];
return [NKLineChartDataItem dataItemWithY:yValue];
};
// Line Chart #2
NSArray * data02Array = @[@0.0, @180.1, @26.4, @202.2, @126.2, @167.2, @276.2];
NKLineChartData *data02 = [NKLineChartData new];
data02.color = NKTwitterColor;
data02.alpha = 0.5f;
data02.itemCount = data02Array.count;
data02.inflexionPointStyle = NKLineChartPointStyleCircle;
data02.getData = ^(NSUInteger index) {
CGFloat yValue = [data02Array[index] floatValue];
return [NKLineChartDataItem dataItemWithY:yValue];
};
chart.chartData = @[data01,data02];
image = [chart drawImage];
[self.chartImage setImage:image];
```
####Bar Chart####
```objective-c
NKBarChart *chart = [[NKBarChart alloc] initWithFrame:frame];
chart.yLabelFormatter = ^(CGFloat yValue){
CGFloat yValueParsed = yValue;
NSString * labelText = [NSString stringWithFormat:@"%0.f",yValueParsed];
return labelText;
};
chart.labelMarginTop = 5.0;
chart.showChartBorder = YES;
[chart setXLabels:@[@"2",@"3",@"4",@"5",@"2",@"3",@"4",@"5"]];
// self.barChart.yLabels = @[@-10,@0,@10];
[chart setYValues:@[@10.82,@1.88,@6.96,@33.93,@10.82,@1.88,@6.96,@33.93]];
[chart setStrokeColors:@[NKGreen,NKGreen,NKRed,NKGreen,NKGreen,NKGreen,NKRed,NKGreen]];
image = [chart drawImage];
[self.chartImage setImage:image];
```
####Pie Chart####
```objective-c
NSArray *items = @[[NKPieChartDataItem dataItemWithValue:10 color:NKLightGreen],
[NKPieChartDataItem dataItemWithValue:20 color:NKFreshGreen description:@"WWDC"],
[NKPieChartDataItem dataItemWithValue:40 color:NKDeepGreen description:@"GOOG I/O"],
];
NKPieChart *chart = [[NKPieChart alloc] initWithFrame:frame items:items];
chart.descriptionTextColor = [UIColor whiteColor];
chart.descriptionTextFont = [UIFont systemFontOfSize:12.0];
chart.showAbsoluteValues = NO;
chart.showOnlyValues = NO;
image = [chart drawImage];
[self.chartImage setImage:image];
```
####Circle Chart####
```objective-c
UIColor *shadowColor = [UIColor colorWithRed:225.0 / 255.0 green:225.0 / 255.0 blue:225.0 / 255.0 alpha:0.5f];
NKCircleChart *chart = [[NKCircleChart alloc] initWithFrame:frame total:@100 current:@60 clockwise:YES shadow:YES shadowColor:shadowColor displayCountingLabel:YES overrideLineWidth:@5];
chart.strokeColor = NKGreen;
chart.strokeColorGradientStart = NKLightGreen;
image = [chart drawImage];
[self.chartImage setImage:image];
```
####Radar Chart####
```objective-c
NSArray *items = @[[NKRadarChartDataItem dataItemWithValue:3 description:@"Art"],
[NKRadarChartDataItem dataItemWithValue:2 description:@"Math"],
[NKRadarChartDataItem dataItemWithValue:8 description:@"Sports"],
[NKRadarChartDataItem dataItemWithValue:5 description:@"Liter"],
[NKRadarChartDataItem dataItemWithValue:4 description:@"Other"],
];
NKRadarChart *chart = [[NKRadarChart alloc] initWithFrame:frame items:items valueDivider:1];
image = [chart drawImage];
[self.chartImage setImage:image];
```
##TODO##
