maby you are ploting num(6:16,1) wich is false,you must use num(:,1)) for the first row and num(:,2) for the second. i don't think you will have an error message

Use xlsread() to get the entire contents of your workbook into a cell array.
[num,txt,raw] = xlsread(filename); % From the help
Then use cell2mat or something to extract out columns into an x array and a y array.
x = cell2mat(num(1:10, 1)); % Untested
y = cell2mat(num(1:10, 2)); % Untested
Then, to plot, use

What does size(num) show? And please show your xlsread() command so we are sure we are talking about the same options.

Almost certainly a spellcheck miss from a non-English speaker attempting "attached".

I guess that makes sense, instead of "verified". However the file was NOT attached - only a screenshot was displayed, no Excel file was attached. Use the paperclip icon.
