Getting zeros when empty

Hi, I am plotting one particular column from a txt file using dlmread. Whenever there is an empty cell (though other columns do have values), I am getting zero values plotted, even though I do not want them. I would like it to read those cells as 'not existing'. Thank you to anyone who can help!

You cannot do that using dlmread(). Use readmatrix() or readtable() or textscan()
