Yes, Prime will not accept a 3D plot from a matrix with just a single row. It's because it (deliberately or inadvertently) was implemented that way:

The work-around (one of the many work-arounds that you need when working with Prime) for this shortcoming is to repeat the matrix row when you want to plot just a single point. This can be done by stacking:

Success!

Hi,

It would appear you need at least two rows in the data to get a scatter plot!

Cheers

In real Mathcad plotting a couple of points was a bit awkward as it needed a nested matrix to do so. This was made a bit easier in Prime.

But Mathcad would also allow to plot a single point and this seems to be broken in Prime. On the other hand, the plot abilities in Prime, and especially the 3D plots, are not really to be taken seriously anyway.

A simple workaround, if you really want to use Primes 3D plot and plot a single point, is to plot the same point twice 😉

Is there any specific reason the same point needs to be plotted twice?
