Plot a Point in 3D Space

[MoeSzyslak]

All -- I have always struggled with the 3D plotting facilities in Mathcad, which I find quite non-intuitive. Where am I going wrong in attempting to plot a single point in space?

Thanks.

If you pass the plot an array it plots the row and column numbers as x and y, and the value as z. You need to pass it arrays for each coordinate, even if they are just single element arrays.

Richard, Jean -- thanks. Sometimes, I am not a very smart man.

The "nesting procedure" in Mathcad,
is more important than mostly important.

If it's of any help, there is a partial emulation of Maple's plottools library in the worksheet at http://collab.mathsoft.com/read?113275,15 . You just need to copy the collapsed area named "plottools emulation" over to whatever worksheet you want and call the appropriate functions.

You can create a single point at (x,y,z)=(1,2,3) by

pt := vec2pt(stack(1,2,3))

and then entering pt into the 3D plot placeholder (setting the "disply as" element of the "general" tab in the 3D dialog box to "scatter plot")

Example attached.
