Different X axis location. Unsure Why.

I am performing two very similar plots but the placement of the xlabel is different and I cant determine why or how to rectify it. I would prefer to force the xlabel to be as in my first example:

%clearing crap
clear all
clf

%selecting amazing font
set(0, "DefaultAxesFontName", "Courier New");
set(0, "DefaultTextFontName", "Courier New");

%importing required data
%importing data
Raman = readtable("Pfile.csv");

%converting data
shift = table2array(Raman(:,1));
MW0 = table2array(Raman(:,2));
AlMW25 = table2array(Raman(:,3));
AlMW5 = table2array(Raman(:,4));

%plotting MW0
plot(shift, MW0)

hold on %plotting on same graph

plot(shift, AlMW25)
plot(shift, AlMW5)

hold off %end of plotting

%beautifying curve
ax = gca;
ax.XAxisLocation = "origin";
ax.YAxisLocation = "origin";
box off;

%labelling graph
xlabel("Raman Shift [cm^{-1}]");
ylabel("Intensity [Arb. Units.]");
title("Raman Spectra")
legend("MW 0","AlMW 2.5","AlMW 5","Location","north west")

This returns the following graph:

In example two i get the following:

%clearing crap
clear all
clf

%selecting amazing font
set(0, "DefaultAxesFontName", "Courier New");
set(0, "DefaultTextFontName", "Courier New");

%importing required data
%importing data
Raman = readtable("Ufile5.csv");

%converting data
shift0 = table2array(Raman(:,1));
NBS0 = table2array(Raman(:,2));
shift1 = table2array(Raman(:,3));
NBS1 = table2array(Raman(:,4));
shift2 = table2array(Raman(:,5));
NBS2 = table2array(Raman(:,6));
shift3 = table2array(Raman(:,7));
NBS3 = table2array(Raman(:,8));
shift4 = table2array(Raman(:,9));
NBS4 = table2array(Raman(:,10));

%plotting NBS0
plot(shift0, NBS0)

hold on %plotting on same graph

plot(shift1, NBS1)
plot(shift2, NBS2)
plot(shift3, NBS3)
plot(shift4, NBS4)

hold off %end of plotting

%beautifying curve
ax = gca;
ax.XAxisLocation = "origin";
ax.YAxisLocation = "origin";
box off;

xlabel("Raman Shift [cm^{-1}]"); % Store handle
ylabel("Intensity [Arb. Units.]");
title("Raman Spectra for NBS Glasses");
legend("NBS 0", "NBS 1", "NBS 2", "NBS 3", "NBS 4", "Location", "northwest");

and i get the followign less optimal xlabel position:

[dpb]

set(0, "DefaultAxesFontName", "Courier New");
set(0, "DefaultTextFontName", "Courier New");
Raman = readtable("Ufile5.csv");
N=5;                                                                % number of shift pairs
Raman.Properties.VariableNames(1:2:2*N)=compose('shift%d',[0:N-1]); % if not named, create desired names
Raman.Properties.VariableNames(2:2:2*N)=compose('NBS%d',[0:N-1]);
for i=1:2:2*N                                                       % plotting NBSn in turn...
  plot(Raman.(Raman.Properties.VariableNames{i}),Raman.(Raman.Properties.VariableNames{i+1}))
  if i==1, hold on, end                                             %plotting on same graph
end
box off;
xlabel("Raman Shift [cm^{-1}]"); % Store handle
ylabel("Intensity [Arb. Units.]");
title("Raman Spectra for NBS Glasses");
legend(Raman.Properties.VariableNames(2:2:2*N), "Location", "northwest");

Remove the XAxis.Location, YAxis.Location change from the default and all will be well.

There's no need to create copies of existing data; use the table.

I created the equivalent variable names in the table for you if they aren't already what is wanted when read in...that's optional but convenient.
