So after testing it , turns out that all the numbers are read as char.

Hi,
try this:
A=csvread('samples.csv',2,0);
plot(A(:,1),A(:,2))
For me it works - there is no problem with your plot function i guess. It is due to the format that the readtable function gives your data when inporting it. I get the same error when i try to use readable... So do not search for a double file that is not there...
Best regards
Stephan

The first two rows are ignored and no columns are ignored when importing the data - so the imported data is only numeric, which is easier to process with.
