Question on how to use scatter3

Hi, I trying to use the function scatter3,

I was able to plot a 2D scatter graph using just X and Y, however I want to make it 3D to allow the user to look around the graph.

Below is my code.

X = linspace(0,time,50);

Y = height-(9.81/2)*(trajectory.^2);

Z = 0;

scatter3(app.UIAxes,X,Y,Z,'ro');

Im not sure what the Z value should be in order to do this, however when I run the program, it gives me the error,

"X, Y and Z must be vectors of the same length."

Any ideas on how to make the 2D graph 3D?

Thanks!

The ‘Z’ vector can be anything, providing it is a vector of the same size as the others. Setting it equal to:

Z = zeros(size(X));

will simply create a 2D plot in 3D coordinates. A much better approach would be to set:

Z = X;

if you want to clearly delineate the points.
