/EChart/ folder into your project
EColumnChart as a example, all ECharts work in a similar way.
Import the head file:
Make your ViewController adopts the EColumnChart's protocol:
@interface YourViewController : UIViewController <EColumnChartDelegate, EColumnChartDataSource>
Declare a EColumnChart instance:
@property (strong, nonatomic) EColumnChart *eColumnChart;
Give your EColumnChart a nice frame:
_eColumnChart = [[EColumnChart alloc] initWithFrame:CGRectMake(40, 100, 250, 200)];
Set EColumnChart's delegate and dataSource to your ViewController:
[_eColumnChart setDelegate:self]; [_eColumnChart setDataSource:self];
Add EColumnChart to wherever you want:
After setting up your EColumnChart, you may need to provide the data for the EColumnChart and you will be able to get events from EColumnChart as well.
If you were a expert with
UITableView, you will be quite familiar with the way
EColumnChart works. Because they work in a same way.
You need to implement every method in the
/** How many Columns are there in total.*/ - (NSInteger) numberOfColumnsInEColumnChart:(EColumnChart *) eColumnChart; /** How many Columns should be presented on the screen each time*/ - (NSInteger) numberOfColumnsPresentedEveryTime:(EColumnChart *) eColumnChart; /** The highest value among the whole chart*/ - (EColumnDataModel *) highestValueEColumnChart:(EColumnChart *) eColumnChart; /** Value for each column*/ - (EColumnDataModel *) eColumnChart:(EColumnChart *) eColumnChart valueForIndex:(NSInteger)index;
The implementation of the Delegate is according to your needs
/** When finger single taped the column*/ - (void) eColumnChart:(EColumnChart *) eColumnChart didSelectColumn:(EColumn *) eColumn; /** When finger enter specific column, this is dif from tap*/ - (void) eColumnChart:(EColumnChart *) eColumnChart fingerDidEnterColumn:(EColumn *) eColumn; /** When finger leaves certain column, will tell you which column you are leaving*/ - (void) eColumnChart:(EColumnChart *) eColumnChart fingerDidLeaveColumn:(EColumn *) eColumn; /** When finger leaves wherever in the chart, will trigger both if finger is leaving from a column */ - (void) fingerDidLeaveEColumnChart:(EColumnChart *)eColumnChart;
