As the title says, I would like to combine a Plot3D object with a Graphics3D object. However, it seems that Show is recalculating the dimensions of the box.

So two questions:

  1. Why is Show recalculating the box? I assumed that the box is created in the Plot3D object?

  2. How do I prevent this? The Graphics3D object is supposed to be a custom-placed axes label, see the example below.

Alternatively, I'd be happy with a solution how to position AxesLabel freely.

P.S.: the only thing I could find was How to have one or multiple Boxed graphics, mixed with non Boxed, in the same Graphics3D but that doesn't explain the issue and is 9 years old so my hope was that some simpler solution popped up since then.

MWE:

some3dplot = Plot3D[x + y, {x, -1, 1}, {y, -1, 1}, Boxed -> True];
someXAyesLabel = Graphics3D[Text["some label", {1, -2, -2}]];
plt = Show[some3dplot, someXAyesLabel, PlotRange -> All]

    $\begingroup$ Welcome to Mathematica StackExchange! The "box" is being "recalculated", because you set PlotRange -> All. If you omit this, then Show will use options from the first of its arguments, namely from your some3dplot, and will not "recalculate" the box. As for the positioning of labels: see Axes Origin & Labels in 3D Plot and Manually assigning Axes label position in Plot3D. $\endgroup$

  • $\begingroup$ Thank you for your answer. I noticed that PlotRange->All causes this, however, if I leave it out I don't see the "some label" anymore... $\endgroup$

    $\begingroup$ Well, of course you don't see it, because you positioned it at {1, -2, -2}, which is outside of the box :) Put it at, for example, position Scaled[{1, 0, 0}]. $\endgroup$

  • $\begingroup$ Well I want to position it outside of the box since it should be an AxesLabel... $\endgroup$
