- (void)drawline:(CGContextRef)contextspa
startPoint:(CGPoint)startPoint3d
stopPoint:(CGPoint)stopPoint继承
color:(UIColor *)colorit
lineWidth:(CGFloat)lineWitdth;class
- (void)drawLabelPrice:(CGContextRef)context;方法
//高亮状态滑动margin
- (void)drawHighlighted:(CGContextRef)context
point:(CGPoint)point
idex:(NSInteger)idex
value:(id)value
color:(UIColor *)color
lineWidth:(CGFloat)lineWidth;
- (void)drawLabel:(CGContextRef)context
