I have a large csv file and try to load it into MATLAB and plot it with timestamp. My release is 2016b and i have 8gb of RAM.
My code starts like this
ds = tabularTextDatastore('2018-11-18.csv','TreatAsMissing','NA')
data = preview(ds);
whos data
data(:,1:7) % Look at first 7 variables
testdata = read(ds)

strcat the first two columns together with a blank between . datetime the result with an InputFormat parameter , which is required for this purpose because datetime cannot figure out fractions of a second by itself .
Now that you have timestamps and values you can prepare to plot . I think your release permitted using datetime as the X axis .
