How To Use
Download and run the EChartDemo project is the best practice to know how to use EChart.
Step 1: Add EChart to Your Project
use CocoaPods with Podfile:
platform :ios, '7.0' pod "EChart"
or Download project here
/EChart/ folder into your project
Step 2: Include ECharts in your View Controller
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:
Provide data & Get events
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;
