how to make drawnow for this figure

Hi

How do i make my figure plot from this to its negative point, so the figure goes back and forward ( the red line on the uploaded figure) in an animated figure:

figure

plot3(x_coor,z_coor,y_coor,'k','HandleVisibility','off');

hold on;

plot3(Px_coor,Pz_coor,Py_coor,'r','HandleVisibility','off');

x_coor = [0 1 2 3 4 5

1 2 3 4 5 6]

y_coor = [0 0 0 0 0 0

0 0 0 0 0 0]

z_coor = [0 0 0 0 0 0

0 0 0 0 0 0]

Px_coor = [0 1 2 3 4 5

1 2 3 4 5 6]

Pz_coor = [0 0 0 0 0 0

0 0 0 0 0 0]

Py_coor = [0 0.0225501852619405 0.0827680826631456 0.169761552175099 0.273470524612610 0.385480815448938

To animate the red line shown in the attached figure, use the below code. Here, pause is used instead of draw to notice that the animation took place.

h = animatedline;
for t = 1:length(Px_coor)
    addpoints(h,Px_coor(1,t),Pz_coor(1,t),Py_coor(1,t));
    pause(0.5);
end

Hi the code did not make the red line go back and forward.

[Devineni Aslesha]

From the above code, the red line animation is shown where the red line starts at the coordinates (0,0,0) and then moves back to the coordinates near to the origin. Do you expect this back and forward movements to be done iteratively?

Hi I wanted the red line go from 0.5 to -0.5 i the y-axis on the figure I uploaded. Such that it simulated the first modeshape of a canteliver beam

[Devineni Aslesha]

Change the coordinates from the code below to move the red line from 0.5 to -0.5 in the y-axis.

x_coor = [0 1 2	3 4 5];
y_coor = [0 0 0	0 0 0];
z_coor = [0 0 0	0 0 0];
Px_coor = [0 1 2 3 4 5 5 4 3 2 1 0];
Pz_coor = [0 0 0 0 0 0 0 0 0 0 0 0];
Py_coor = [0 0.0225501852619405	0.0827680826631456 0.169761552175099 0.273470524612610 0.385480815448938 -0.385480815448938 -0.27347052461261	-0.169761552175099	-0.0827680826631456 -0.0225501852619405 0];
figure(1)
plot3(x_coor,z_coor,y_coor,'k','HandleVisibility','off');
hold on;
h = animatedline;
for t = 1:length(Px_coor)
    addpoints(h,Px_coor(1,t),Pz_coor(1,t),Py_coor(1,t));
    pause(0.8);
end
