Path of an object

[karryli]

Hi everyone, I have a quesiton about showing a trajectory or more precisely a part of object's updated trajectory. In the following code I try to plot two different trajectories of the same object on the same graph; and one trajectory motion is always a step late to the other one. This is the primitive type of the trajectory model, because it only plots the past n-1 position.

But somehow my code doesn't work. Can anyone give a help?

If I'm understanding your problem correctly, you just have the plot display wrong for your second plot.  Extend the Plot Legend to show the second plot.  Change the plot type to match that of the first plot.

Thanks. I should be more careful.
