An Objective-C class that makes it easy to display data as a line graph on iOS

Usage

The following steps will create a basic instance of OVGraphView:

1. Add all the files from the OVGraphView group in the Xcode project.

2. Import OVGraphView.h and OVGraphViewPoint.h

3. Use the following code to create the instance and add it to the view hierarchy

     OVGraphView *graphview=[[OVGraphView alloc]initWithFrame:CGRectMake(0, 0, 480, 300) ContentSize:CGSizeMake(960, 300)];
     
     //customizations go here
     
    [self.view addSubview:graphview];
   
    [graphview setPoints:@[[[OVGraphViewPoint alloc]initWithXLabel:@"today" YValue:@3.2 ],[[OVGraphViewPoint alloc]initWithXLabel:@"yesterday" YValue:@4 ],[[OVGraphViewPoint alloc]initWithXLabel:@"3" YValue:@6 ]]];
   

Customizations

	graphview.plotContainer.reverse=YES; //reverse the item order and automatically scroll to the right.

	graphview.plotContainer.graphcolor=[UIColor ...];//set the color of the graph
