I have data from a projectile. I have x and y positions. I also have a vector with corresponding time data for the x and y positions. I want to plot the projectile path ( x vs y) as an animated line where points are produced at the time in the corresponding time vector. I would also like to display a timer if possible.

Here's a review of 3 animation techniques.

If you get stuck, show us what you've got and describe the problem so we can focus in on it.

Thanks! But none of these techniques incorporate time vector. I have three vectors xPos, yPos, and Time.

xPos= [0.266 0.8903 2.033 3.5614 5.564 8.0130];
yPos = [0.8307 3.3228 7.4763 13.2911 20.7674 29.9051];
Time = [0 0.2 0.4 .6 0.8 1];

This is just a sample of my data. It is the first second. I want the data to plot over time where corresponding to the time vector.

All three methods demonstrate general approaches to animation. Could you explain why they don't work with your intentions?

Could you explain, or better yet, show us what plot you're making with those three variables?
