Making data files to the same length

I have a set of data files that starts from frame 0 through frame 'n'. 'n' varies from one file to another. When I plot my graph, my plots are of different lengths. What do I do if I want to make them all of the same length. I know there is something that we could do on Matlab, but I lost touch of it.

Answer 1

 >> set(gca,'XLim',[0 100])

will fix the x-axis to run from 0-100. Is that what you mean?

I think he wants all his plots to be the same length (even if they have different lengths.)

I need to cut off some extra data so that my 'n' is the same in all files and the plots have the same limit.

I defined the least and max value of X axis and plotted it. works well! Thank you so much!

I've come across this problem too, and my method (although not the simplest, nor most efficient) is to create x vectors to match your data sets. (ie one x vector for each of your data sets) The x vector you use linspace.

ie 3 data sets, where n = 50, 100 and 500.

x1 = linspace(1,100,50)
x2 = linspace(1,100,100)
x3 = linspace(1,100,500)

hold on
plot(x1,data1)
plot(x2,data2)
plot(x3,data3)
hold off

But I have too many files. I can't do it for all of them one by one.
