大师，为什么折线点 都是在中间，而不是 ……

作者辛苦了，我有幸用到这个库，使用很方便也很好用，但是我实现出效果后，发现最大值和最小值不能显示小数点，我看了下代码没找到修改的位置，能提示下在哪修改吗

• (NSArray *)UUChart_xLableArray:(UUChart *)chart{
  return [self getXTitles:7];
  }
• (NSArray *)getXTitles:(int)num
  {
  NSMutableArray *xTitles = [NSMutableArray array];
  for (int i=0; i<num; i++) {
  NSString * str = [NSString stringWithFormat:@"R-%d",i];
  [xTitles addObject:str];
  }
  return [xTitles copy];
  }
  x轴是这样写的，但是最终显示是这样

求楼主指导，不甚感激

曲线图有办法左右滑动吗？代码里貌似只有柱状图才能左右滑动。

我是在一个view里面添加了折线图，设置了delegate和datasource的代理为view，在里面实现了代理方法，根据服务器返回的值，设置数据后，2条曲线，前面都会重叠，点击显示时，值又是对的，比如，有一条曲线的值是 9341.00,9300.00，9200.00，838500.00，838500.00，838500.00，838500.00 ，第二条曲线的值，0，0，0，0 ，0，0，0，可是2条曲线，前面都重叠了，点击第一个点后，显示出来第一条曲线的值又是9341.00，我不知道是不是我哪里弄错了，还请帮忙解答一下。

如何重新绘制？strokeChart 不会清除之前绘制的，没有相关方法调用重绘？ 怎么解决？

我发现你的UUBarChart有scrollview，为什么UULineChart不添加呢。

UUBar.m中的

• (void)drawRect:(CGRect)rect{
  //Draw BG
  CGContextRef context = UIGraphicsGetCurrentContext();
  CGContextSetFillColorWithColor(context, [UIColor whiteColor].CGColor);
  CGContextFillRect(context, rect);
  }

換成CGContextSetFillColorWithColor(context, [UIColor clearColor].CGColor);
背景的barchart变成黑色
如何更改成透明的？

有办法做散点图吗

请问您这个Library具体是怎样使用的呢？能不能给个例子？
