写了lines、RKLineView、getData三个对象完成实现。
首先开始调用
rkLine= [[RKLineViewalloc]init];
CGRectframe =riKView.frame;
frame.origin=CGPointMake(0,5);
frame.size=CGSizeMake(315,219);
rkLine.frame= frame;
rkLine.xWidth=315;
rkLine.yHeight=219;
rkLine.kLineWidth=4;
rkLine.kLinePadding=1.25;
rkLine.riKArry= [dicobjectForKey:@"rows"];
[riKViewaddSubview:rkLine];
[rkLinestart];//线图运行
其它3个对象部分代码如下
#import
