Multiply your x by 10^12.

bar(x*1e12, y, 1);
xlabel('Time Difference in picoseconds');

this gives me error

here is the part of the code

x = (tin-tex)*(-1.433426304e-12)

hi= histogram(x)

ylabel('number of Ocuurance','fontsize',10);

xlabel('Time Difference in picoseconds');

bar(x*1e-12, y, 1);

I said to use bar, not histogram. If the data is a histogram, then use histcounts to get the y data (counts) or else pass 'Edges' in to histogram

x = (tin-tex)*(-1.433426304e-12) 
[counts, edges] = histcounts(x);
ylabel('number of Occurrences', 'FontSize', 15);
xlabel('Time Difference in picoseconds' 'FontSize', 15);
bar(edges(1:end-1), counts);

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
