How do I create multiple x,y scatters on one plain, and show the "trajectory" of each point?

Suppose I have the following multidimensional matrix, where rows are combinations of x and y values, and the third dimension holds different samples of such combinations:

[x,y,S]

Now I wish to create S scatter plots on the same plain, and I can of course use "hold on" to achieve this as I loop through the third dimension. However, I also wish to show the evolution or trajectory of each combination by joining combinations with a line, which I don't know how to do.

How is that done?

Could you post a small data sample? I am confused about how your data is arranged.

Hello,

You could try using the animatedline command

Essentially, every time you would add data from the third dimension, you could update the line objects with new (x,y) values as explained in the documentation.

Of course, depending on your use case, you might want to avoid creating too many line objects in interest of saving memory.
