Misalignment Ticks and Line when changing linewidth

So I'm getting a misalignment between a line and my ticks, using version R2016a (and can't update it on the pc that is using it).

I can't find any matlab code that let's me fix this, I looked up the code to control ticks and ticklabels.

my code is below:

Pos_size=[100 100 800 400];

FSax=12;
FWax='bold';
FStitle=16;
FWtitle='bold';
MkSz=20;

Tfig5='Voltage vs FWHM';
Xlab4='Applied potential (V)'; %figs 4 and 5 
YlabL1='CPM (M)'; %figs 1 and 2 and 4 and 5

%% plotting figure 5 
h5=figure(5);
title(Tfig5,'FontSize',FStitle,'FontWeight',FWtitle)
xlabel(Xlab4,'FontSize',FSax,'FontWeight',FWax)
ylabel(YlabL1,'FontSize',FSax,'FontWeight',FWax)
set(h5,'Position',Pos_size);
hold on
ylim([0 400]);
hax5(1)=plot(Voltage,FWHMVolt,'.-','Linewidth',2,'MarkerSize',MkSz);
ax5=h5.CurrentAxes;
set(ax5,'FontSize',FSax,'FontWeight',FWax,'LineWidth',1);
line([0 0], get(ax5, 'ylim'),'color',[0.7 0.7 0.7],'linestyle','--','Linewidth',1.5); % this is my line (in my actual script I use vline but that's a file from mathworks but does the exact same) -> vline(0,'color',[0.7 0.7 0.7],'linestyle','--','Linewidth',1.5);
box on

% data if someone wants to run the code themselves
Voltage =

   -0.1000
         0
    0.0100
    0.0300
    0.0500
    0.0700
    0.1000
    0.3000
    0.5000
    0.7000
    0.9000
    
FWHMVolt =

    50
   146
   145
   143
   141
   141
   145
   244
   304
   334
   351

PS I also tried

plot([0 0],get(ax5, 'ylim'),'Linewidth',1.5)

Same issue as before

What will happen if you change linewidth?

[Bob photonics]

While chnaging the linewidth for the line (or plot) will leave the same issue, it just becomes less obvious when you make it thicker.

Increase the linewidth of the axes (ticks) increase the problem ever so sligthy (need to go to 4 or more for it to be obvious). Which is exactly what I expected to be honest because it was the what I changed (I increased it from the normal size to 1).

Nonetheless I need this higher value as otherwise the ticks/axes are not clear/obvious enough in my opinion.

See linewidth 6 in the image I attached:

Hi,

I could not reproduce the same in MATLAB R2019b. If it is not okay for you to update to recent versions, then you could try moving your line to align with the ticks as a workaround.

Thanks for the suggestion it works but will be a hassle.

This will definitely work as long as I don't want to change the linewidths anymore but I'm afraid it will change again if I change the linewidths.

If anyone has a better suggestion or a solution that will work permanently I would still love to hear it.

Anyway I also tested it in 2018a and had the same issue. At work we are still using 2016a on servers ona lab PCs, while on our personal computers we have 2018a. We don't have much control over updates as that's controlled by ICT.

Ps to some this might not look like a big deal, but if you're using a projector, that projects on an entire wall over 3meters wide or you print out A0 posters then this magnified and a lot more obvious.
