How to move the data to the right

I have 9000 speed data(S1 to S9000) related to 9000 time data(T1 to T9000). And now I want to move the speed to the right, which means I need to increasing T. For example, I will increase h, then the time is from T1+h to T9000+h, but the speed at T1+h is still S1, and S9000 would be at T9000+h.

How is your data structured in MATLAB? Do you have any code put together already?

How exactly are you 'moving' the speed to the right? I understand adding a value to time to get a new set of consecutive values, but how are you defining your speed values for the previously undefined times? In other words, if i is the interval between times, then T9000+i = T9001, but what is S9001? How does it relate to S9000?

Actually, I just want to make my start point move to the right. For example, my plot start from t=0, and now I want it start from t=i.（time is in x axis, and speed is in y axis）

Sounds like you just need to adjust your range for your plot then.

plot(t(h:end),s(h:end));

This doesn't cover the T9001:T9000+h, range, but you won't have any data there anyway from the sounds of things.

Thank you!

It sounds like you need to shift the data to the right by adding a constant value to the x-coordinates and then assign the orginal x-coordinates (time) to the axis tick labels by setting the XTickLabel. If this is not clear or does not solve the problem, please elaborate.

Yes. For example, my plot is start from t=0, and now I want it to start from t=h.

Are my suggestions clear?

Yes. Thank you!
