How can I plot accleration in the x, y, and z directions? Each accerlation coordinate a(x,y,z) is associated with a moment in time.

I have used an accelerometer to capture data. It takes readings at 50Hz in 3 directions. All of these acceleration points are also associated with a time.
For example:
t1 = 0.02s; ax1 = 1; ay1 = -1; az1 = 1.5;
All of this data is in excel and I've imported for use. I would like to be able to see how all three change as time moves, but having three plots of
x, y, t with z constant
y, z, t with x constant
z, x, t with y constant
would be acceptable too. I initially tried scatter3 with all the acceleration points, but it returns no valuable information as there is no way to see how these points came about in relation to time.
I've also thought an animated 3D plot where the point in space changes over the length of the animation. But that's way out of my league.

Would a simple 2D plot suffice? E.g.,
plot(t,x,t,y,t,z);
grid on
legend('x','y','z');
xlabel('time')
ylabel('acceleration')
