Thanks Jan. This is my code. data=xlsread('DataTest','Sheet1'); q=data(:,2); time=data(:,1);
Error message
Attempted to access data(:,2); index out of bounds because size(data)=[193,1].
Matlab is not reading the first column of the excel file that contains the date so it takes the second column as the first column as a result it could not find second column. Please help

Hi, I have this code wt=xlsread('DataTest','sheet1'); datecol = 1; wt(:,datecol) = wt(:,datecol) + datenum('30-Dec-1899'); x=wt(:,1); qo=wt(:,2); plot(x,qo);
How do I use datetick to get the x (date axis) in day-month-year ('dd-mmm-yyyy') format? Thanks Isa
