Vertical lines on a graph from a CSV

Hi,

I have a CSV file that has many elements and their emission line at a specific wavelength. On my graph I want to draw all these straight vertical lines for each element. The graph is Wavelength against intensity.

I currently am able to manually enter in each line using

Lyman_alpha = vline(937.06,'r','Lyman Alpha')

Where 937.06 is the wavelength and r makes the line red.

However I have over 60 emission lines to place on my graph, is there anyway this can be done with a few lines of code? I tried this but failed miserably

emissionlines =csvread('emissionlines.csv');
element = emissionlines(:, 1);
wavelengthEmission = emissionlines(:, 2);

element[i] = vline(wavelengthEmission[i],'r','element[i]')   <--- Fails here
findpeaks(SFD,wavelength,'Threshold',6)

PS. I'm new to MATLAB.

[KSSV]

try

hh = vline(wavelengthEmission[i],'r','element[i]')
