Hello, I want to make a Matlab plot with the months of the year on the x-axis. I am trying to plot a total of 17520 readings (48 per day) on the y-axis and then show the months on the x-axis. The problem with the code I am using now is that the vectors are different lengths (b is 12 and a is 17520).
Here is my code:
function [y] = doc_concentration
a = xlsread ('DOC_Conc_2007-2011.xlsx',1,'A3:A17522');
startDate = datenum('01-01-2007');
endDate = datenum('12-31-2007');
b = linspace(startDate,endDate,12);
length(a)
length (b)
plot (b,a)
set(gca,'XTick',g)
datetick('x','mmm','keepticks')
end
Can anyone help? Thanks in advance.

Please format your code properly using the "{} code" button. I've done this for you this time.
