How to use plot3 and a for loop to gradually plot the 3D graph of values?

Hello there!

I have 3 arrays describing a 3D motion XYZ. I would like to plot them gradually to generate a "simulation" of the 3D motion of the point in space.

I have tried to use a for loop with plot3 but it just gives me a blank figure.

Any suggestions?

Thank you in advance.

for i=1:20
    plot3(X(i),Y(i),Z(i))
end

figure
hold on
for i=1:20
    plot3(X(i),Y(i),Z(i),'.r')
end

You have to use a marker when you are plotting a single point.

Another way.

for i = 1:20
plot3(X(1:i),Y(1:i),Z(1:i),'r')
end

Thank you KSSV can I ask you what (X(1:i)) does exactly?

X(1:i) will pick the array from 1 to i. They are indices.

Thank you is accpeting the answer. :)
