I do not know if this would work for ‘.dat’ files, but it works for the ‘.txt’ file you posted:
T = readtable('switch.txt', 'HeaderLines', 5, 'Delimiter','\t','ReadVariableNames',false);
Time = T.Var2;
iv1 = T.Var3;
figure(1)
plot(Time, iv1)
grid

Hi guys, I have a similar problem. I saved some data in a .dat file. I can load the data to matlab and it saves it in an array but I don't know how to plot a graph using the data. Any help would be appreciated.

download my txt file now take star strider's code to the command line of matlab and see how it works try to use matlab 2013. as text scan function is provided in latest version
if you get any idea from it then you could simply chang yours
be sure when working with your file change the .dat file to .txt and run the code search for cell2mat function and textscan function in matlab help
