Contribution Graph
The contribution graph mimics the GitHub one. You can implement theTEAContributionGraphDataSourceprotocol to provide data and customize the style of the graph. The required methods are:
// The DataSource should return an NSDate that occurs inside the month to graph - (NSDate *)monthForGraph; // The day variable is an integer from 1 to the last day of the month given by monthForGraph // Return the value to graph for each calendar day or 0. - (NSInteger)valueForDay:(NSUInteger)day;
There are currently three more DataSource methods to customize the coloring of the graph. Each grade is represented by a different color.
// Defines the number of distinct colors in the graph - (NSUInteger)numberOfGrades; // Defines what color should be used by each grade. - (UIColor *)colorForGrade:(NSUInteger)grade; // Defines the cutoff values used for translating values into grades. // For example, you may want different grades for the values grade == 0, 1 <= grade < 5, 5 <= grade. // This means there are three grades total // The minimumValue for the first grade is 0, the minimum for the second grade is 1, and the minimum for the third grade is 5 - (NSInteger)minimumValueForGrade:(NSUInteger)grade;There’s also a method to define the tap behavior on contribution graph cells:
- (void)dateTapped:(NSDictionary *)dict;
Here is a simple sample of implementing the delegate methods after connectingdelegatein Interface Builder.
#pragma mark - TEAContributionGraphDataSource Methods - (void)dateTapped:(NSDictionary *)dict { NSLog(@"date: %@ -- value: %@", dict[@"date"], dict[@"value"]); } - (NSDate *)monthForGraph { // Graph the current month return [NSDate date]; } - (NSInteger)valueForDay:(NSUInteger)day { // Return 0-5 return day % 6; }Clock Chart
// This sample uses Storyboard @property (weak, nonatomic) IBOutlet TEAClockChart *clockChart; self.clockChart.data = @[ [TEATimeRange timeRangeWithStart:[NSDate date] end:[NSDate dateWithTimeIntervalSinceNow:3600]], // ... ];Bar Chart
Just a bar chart, no interaction, no animation.
#import "TEAChart.h" TEABarChart *barChart = [[TEABarChart alloc] initWithFrame:CGRectMake(20, 20, 100, 40)]; barChart.data = @[@2, @7, @1, @8, @2, @8]; [self.view addSubview:barChart];
To add colors to the bar chart, add an array of colors
#import "TEAChart.h" TEABarChart *barChart = [[TEABarChart alloc] initWithFrame:CGRectMake(20, 20, 100, 40)]; barChart.barColors = @[[UIColor orangeColor], [UIColor yellowColor], [UIColor greenColor], [UIColor blueColor]]; barChart.data = @[@2, @7, @1, @8, @2, @8]; [self.view addSubview:barChart];To add x-labels to the bar chart, setxLabelsproperty. Should be just one character per label since the bars are narrow.
barChart.xLabels = @[@"A", @"B", @"C", @"D", @"E", @"F"];
