MATLAB: Turning a time-based X-axis into equal percentages

x-axis percentages

Much of the data I work with are forces over time. Unfortunately, time is never the same between two trials (see attached photos). I would like to take this time data and divide it into 10 equal blocks from start to finish (i.e., 0-10%, 10-20%, 20-30%,…….90-100%). This way I can compare what happens between trials. Any suggestions?
As a secondary question, I am interested in getting specific values out of these percentage blocks (i.e., max between 20-30%). Thoughts?
Thank you for all of your help.

This was the code I was able to use to get the x-axis into a percentage. I had to do other filtering things first, because of the nature of my data.
Thanks Sara
zmax = max(Fzfilt); start=zmax/10; ind1 = find(Fzfilt >= start, 1, 'first'); ind2 = find(Fzfilt >= start, 1, 'last');
t1 = t(ind1); t2 = t(ind2);
tscale = (((t(ind1:ind2)-t1)/(t2-t1))*100)
