How to make a sequence of time and the corresponding data from a data set where time is not provided sequentially

I have some time series data for velocity, density for 30 mins time gap. But when I plotted, I see the time overlaps. How can I make the data set sequential for time with the corresponding data?
Can I do it without interpolation?
Thanks for help!
Suppose time = [1, 5, 10, 15, 20, 16, 21, 26, 31] and velocity and density are for the corresponding time.

Ran in:
You cannot fill the gaps in your data without physically taking more data or interpolating.
However if your problem is to order the time vector so that it is strictly increasing then you can use sort function:
time = [1, 5, 10, 15, 20, 16, 21, 26, 31];
data = [10 20 25 30 35 27 36 40 45];
[timeSorted,idx] = sort(time);
dataSorted = data(idx);
subplot(2,1,1),plot(time,data,'bx-'),xlim([0 32]),title('Original Data')
subplot(2,1,2),plot(timeSorted,dataSorted,'rx-'),xlim([0 32]),title('Sorted Data')
