采用继承的方法，写了个基类，，重写- (void)drawRect:(CGRect)rect 方法，setNeedsDisplay 调用drawRect方法；

- (void)drawline:(CGContextRef)context

      startPoint:(CGPoint)startPoint

       stopPoint:(CGPoint)stopPoint

           color:(UIColor *)color

       lineWidth:(CGFloat)lineWitdth;

 

- (void)drawLabelPrice:(CGContextRef)context;

 

//高亮状态滑动

- (void)drawHighlighted:(CGContextRef)context

                  point:(CGPoint)point

                   idex:(NSInteger)idex

                  value:(id)value

                  color:(UIColor *)color

              lineWidth:(CGFloat)lineWidth;

 

 

- (void)drawLabel:(CGContextRef)context

   attributesText:(NSAttributedString *)attributesText

             rect:(CGRect)rect;

//画柱状图

- (void)drawRect:(CGContextRef)context

            rect:(CGRect)rect

           color:(UIColor*)color;

 

 

- (void)drawGridBackground:(CGContextRef)context

                      rect:(CGRect)rect;
