Hope you can help. Thanks in advance.

fill(x2, inBetween, 'k');

It would be easier if we had your data so we could test on our own system to avoid accidentally giving you a solution that does not work for your situation.

Plot everything (including the patch calls) using linear axis rulers first, then convert the scale to logarithmic.

@Saugat Shrestha — It would have helped to have had your data at the outset. As Walter points out, the problem is that ‘f_Along’ begins with 0. Since log(0) appraches -Inf, the transformation fails for patch.
Add before you create ‘figure(2)’:
f_Along = f_Along + eps;
and after the patch (or fill) call:
xlim([f_Along(2) f_Along(end)])
set(gca, 'XScale','log')
@Walter — Thank you.
