我有一个函数可以根据任意数量的字典(每个字典代表图表上的一条线)生成 XY 散点图,每个字典都包含一个日期键和一个数值。到目前为止,这些值似乎在 Y 轴上有效,但日期轴 (X) 似乎已损坏。每次我从字典中将系列添加到图表中时,当我特别想要一个散点图时,它都会将其强制为条形图。如果我在分配后将其强制返回散点图,则它完全拒绝显示日期轴。
这里有些例子。
我希望图表看起来像这样
如果我告诉它不要使用日期,图表看起来像这样
当我专门将系列的数据类型设置为 xlDate 时,图形变为此。它神秘地变成了条形图
如果我在将其设置为使用 xlDate 后专门将其更改回散点图,它看起来像这样
任何帮助将不胜感激。这是我的 VBA 代码
