I searched Google and on many different forums but cannot find the Physical Nature (I don't know to say it) of an Embedded Chart's container window, I mean the canvas like rectangular area which serves as, well, the chart container.
I know that it is a ChartObject.
The main clarifications that I needed is:
Is it a Shape as in Autoshape or Freeform shape? (I suspect so) It does show up as a shape in Selection Pane. Copy/Pasting Freeform shapes onto it causes pasted shapes to stick onto it while doing the same with any other two shapes won't stick to each other.
Is it a Userform? (I am skeptical) But Userforms are always in front of the shapes and shapes cannot be pasted onto userforms obviously.
