Question

我认为Flex图表存在漏洞。

“DATETIME AXIS在某些情况下不支持系列堆叠，而线性轴和类别工作在相似的条件下工作”

当每个系列都有其独立的数据提供者时，会发生“群集”和“堆叠”类型。如果为数据提供者分配了图表本身，它将正常工作。

下面的代码工作正常（1）'c.dataprovider = annualdata; '没有评论（2）'series1.dataProvider = annualData2;'被评论。（3）'series2.dataProvider = annualData2;'被评论

但是，如果使用类别轴或线性轴，那么代码工作正常，无论我们如何分配数据提供者。代码粘贴在下面供您参考。

“这是一个错误的错误，还是我错过了什么？”

我非常需要它，请帮忙。

提前致谢。
