how can i make a growing time vector, that fits my data vector?

I have a for loop that loads in a sample of data and stores it in array for each iteration of the loop. I also want to plot the data together with time, one time for each iteration, but to do that need a growing time vector that has same length as my data array, which is updated every iteration. It look something like this.
t = 0;
for i = 1:20
pause(1)
Data(i) = LoadData()
t(i) = t(i)+1;
plot(t,Data)
end
but the problem is that as i initialize my timevector 't' it is allready bigger than my datavector 'Data', by one. But I need to initialize it, because i want it to start from zero. I thought this would be simple to solve, but maybe I am tired. I have tried different things, but I just can't figure it out.
If anybody know how to this, please help.

It is solved
t = 0;
for i = 1:20
pause(1)
if i==1
t(i)=0
else
t(i)=t(i-1)+1
end
Data(i) = LoadData()
t(i) = t(i)+1;
plot(t,Data)
end

Can't you just
plot( (0:(i-1), Data )
instead?

Apparently not.
I deleted my Answer that did essentially the same thing (using the length of ‘Data’ to create ‘t’ after the loop).
