XYChart is designed for line & bar of charts which can compare mutiple datas in form styles, and limited the range of values to show, and so on.
| LineChart | BarChart |
|---|---|
 |
 |
| single datas in linechart | single datas in linechart |
 |
 |
| mutiple datas in linechart | mutiple datas in linechart |
 |
 |
| LineDotsClicked: show all if the dots closed | BarClicked: custom click effects |
 |
 |
| scrolling linechart (did set row width) | scrolling barchart (did set row width) |
Usage
@interface XYChart : UIView<XYChartContainer>
@property (nonatomic, weak, nullable) id<XYChartDataSource> dataSource;
@property (nonatomic, weak, nullable) id<XYChartDelegate> delegate;
@property (nonatomic, readonly) XYChartType chartType;
- (instancetype)initWithFrame:(CGRect)frame chartType:(XYChartType)chartType NS_DESIGNATED_INITIALIZER;
@end方法1：
_chartView = [[XYChart alloc] initWithFrame:CGRectMake(0, 0, 300, 100) chartType:XYChartTypeLine];
_chartView.dataSource = self;
_chartView.delegate = self;
[self.view addSubview:_chartView];方法2：
// ChartGroup is the child of XYChartDataSourceItem
_datasource = [[ChartGroup alloc] initWithStyle:XYChartTypeBar section:2 row:15 width:60];
_chartView = [[XYChart alloc] initWithFrame:CGRectMake(0, 0, 300, 100)
chartType:XYChartTypeLine];
_chartView.dataSource = _datasource;
[self.view addSubview:_chartView];XYChartDataSource
