[Octave-bug-tracker] [bug #40898] scatter3 needs better input validation

[Rik]

Update of bug #40898 (project octave):

                Category:   Plotting with gnuplot => Plotting               
                 Summary:        scatter3 failure => scatter3 needs better
input validation

Follow-up Comment #3:

The sample code is not calling scatter3 correctly.  I changed the Summary for
the report to "scatter3 needs better input validation".  The error message
currently given is too obscure.

>From the documentation,


The color of the markers is determined by C, which can be a string
defining a fixed color; a 3-element vector giving the red, green,
and blue components of the color; a vector of the same length as X
that gives a scaled index into the current colormap; or an Nx3
matrix defining the RGB color of each marker individually.


The calling code is:


c=rand(n,3);
scatter3 (x(:), y(:), z(:), s(:), c(:), "s");


which means that C is a column vector of size [3*N, 1] which doesn't
correspond to any of the allowed formats.

If the function is called with an Nx3 matrix (1 RGB color for each point) then
it works.


scatter3 (x(:), y(:), z(:), s(:), c, "s");
