wrong component, changed to chart and re-assigned to owner of component.

@BM: As Owner of an Mac pls have a look.

Is this really an issue for you? I have observed Excel. If you take a simple bar
chart, you have the y-axis up. When you change this to 3d, the chart looks
almost exactly the same, only the bars look "3d". Then you have an x-axis for
categories, no y-axis and a z-axis that represents the same as the y-axis did
before. I, personally, find this more confusing than calling the axis the same
as before. BTW., in Excel the axis pointing upin a 3d chart is identical to the
axis pointing up in a 2d chart (internally). The only difference is in the UI.
(For whatever reason).

Apart from that, in mathematics it is not required that the z-axis points up,
it's just convention of some (maybe most) people. In computer graphics it is
common to have the z-axis pointing out of the 2d plane, and x and y is like in
2d. (This reflects also the rationale for calling the order of 2d objects
z-order). So we are doing it like in computer graphics (just that z points into
the other direction).

I don't see as an issue. One might think about dropping those letters completely
and talk about value-axis, category-axis and series axis (like Excel does in
addition to the letters). But I don't think renaming would make things clearer
to anyone (including mathematicians, who generally call their axes x_0, x_1, x_2
..., x_n if they happen to have finite coordinate systems ;-) )

BTW. this is not a Mac Issue, therefore I changed the Platform.

->saddington: Sorry, that I closed this bug already. That was maybe a bit fast.
If you still have concerns, please reopen this issue.
