Syntax
[x, y] = getpoints(h)Returns the x and y coordinates of the animated line h.
[x, y, z] = getpoints(h)Also returns the z coordinates of a 3-D animated line.
Description
An animated line grows as points are added to it with addpoints. getpoints reads the points back, which is useful when the data was produced inside a loop and not kept in a variable. clearpoints empties the line.
Input arguments
h- Handle created by
animatedline.
Output arguments
x, y, z- Coordinates of the points added so far with
addpoints.
Example
Read back the points
h = animatedline;
addpoints(h, [1 2 3], [4 5 6]);
[x, y] = getpoints(h)Output
x = 1×3
1 2 3
y = 1×3
4 5 6
