FDGraphView

FDGraphView is an UIView subclass I created for Libretto. It was built using the CoreGraphics’ APIs.

Usage

FDGraphView

Add FDGraphView.{h,m} to your project, import the header where you want to use this component and here you go:

FDGraphView *graphView = [[FDGraphView alloc] initWithFrame:CGRectMake(10, 130, 300, 200)];

graphView.dataPoints = @[@1, @2, @5, @12, @30, @100];

[self.view addSubview:graphView];

A few style-related options are available, look in the header file.

// Style
@property (nonatomic) UIEdgeInsets edgeInsets;
@property (nonatomic) CGFloat dataPointsXoffset;
// -- colors
@property (nonatomic, strong) UIColor *dataPointColor;
@property (nonatomic, strong) UIColor *dataPointStrokeColor;
@property (nonatomic, strong) UIColor *linesColor;

FDGraphScrollView

This is a subclass of UIScrollView that serves as a wrapper around FDGraphView.

Add FDGraphScrollView.{h,m} to your project, import the header where you want to use the component:

FDGraphScrollView *scrollView = [[FDGraphScrollView alloc] initWithFrame:CGRectMake(10, 130, 300, 200)];

// data
scrollView.dataPoints = @[@1, @2, @5, @12, @30, @100, @123, @44];

[self.view addSubview:scrollView];

This is the result:

TODO

If you want to help here are some ideas:

• [ ] Add more styling options
• [x] Create an UIScrollView wrapper to display larger data sets
