Unit of the MarkerSize in a 3D plot?

Hi, I would like to know what the unit for the markersize in a 3d plot is. I have scanned around and saw that it is in something like in "point. But then what does that mean? Is it the radius of the spheres that appear as the markers? Or is point in units cubed, and thus the volume of these markers?

Doesn't matter if your plot is 3D, it is still rendered on a 2D plane.

Alright fair enough, so is point the radius of the circle or the area of it?

If Mathworks sticks to the definition of point, it should be the height of the Marker.

In a perfect world 1 point = 1/72 inch.

Might not look like that on your screen because of reasons (long story) but it should look fine on a (not-scaled) printout.

Alright, so a 8-point marker has diameter 8.

It very much depends. I am not an expert in typography, but for a font whose size is given in points that doesn't mean that all characters will have the same actual size.

Just look at this text, different letters, different heights but the font size is the same for all.

I figure the same applies for Markers. So the actual screen (or paper) size will depend on the size (in points) and the actual marker (character).

In short, unless you want to go down the rabbit hole, the best bet to find something that satisfies your needs is trial and error.

Fairs okay thank you. Good stuff you ve given me :)
