Plotting multiple vertical lines with a for loop

I need to plot vertical lines on a graph at points defined from an array imported from an excel file.
Samples = xlsread('ProjectData.xlsx','Sampling Strategy','A6:B44');
SampleDepth = Samples(:,2);
for i = 1:SampleDepth
xline(i);
end
SampleDepth is a 29x1 double. I need it to plot a vertical line (hence using xline) for each depth specified. I thought that using a for Loop like this would therefore plot a vertical line at each specified point, but Matlab returns:
Error using xline (line 29)
Must pass in a value.
Error in IsotopeGraphs (line 24)
xline()
What needs to be done to fix this? Can xline even be used like this or does it not work?

You cannot draw a line with single point..you need to have two points...read the documentation.
what is xline by the way?

You seem to have a function named xline() which is shadowing the built-in function xline(). Check the output of
which xline
and if it is not something like
.../toolbox/matlab/specgraph/xline.m
then change its name to something else.

Try this
sz = size(SampleDepth,1);
for i = 1:sz
xline(SampleDepth(i));
end

SampleDepth is a matrix so cannot be used to generate the for loop.
I think you meant to use the length of SampleDepth
for i = 1:length(SampleDepth)
