how do I use datetick for this code?

A = textscan(fopen('7633_Flux_AmeriFluxFormat_3.dat'),'%f %f %f %f %f %f %f %f %f %f %f %f %f %f %s %s %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %s %s %f %f %f %f %f %f %f %f', 'Delimiter',',','Headerlines',1);
A_time = A{1,1};
B_time = num2str(A_time);
x_serial = datenum(B_time,'yyyymmddHHMM');
x = datetick('x','dd-mmm-yyyy HH:MM:SS','keeplimits')
CO2 = A{1,3};
figure()
plot(x,CO2)

this is the first part of my code. my x-axis is currently in matlab serial numbers. When I try running this, it says there are too many output arguments in the datetick line. I've never used datetick before. Please tell me what i'm doing wrong and how to fix it

I would code it differently:

fidi = fopen('7633_Flux_AmeriFluxFormat_3.dat');
A = textscan(fidi,'%f %f %f %f %f %f %f %f %f %f %f %f %f %f %s %s %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %s %s %f %f %f %f %f %f %f %f', 'Delimiter',',','Headerlines',1);
fclose(fidi);
A_time = A{1,1};
B_time = num2str(A_time);
x_serial = datenum(B_time,'yyyymmddHHMM');
CO2 = A{1,3};
figure()
plot(x,CO2)
datetick('x','dd-mmm-yyyy HH:MM:SS','keeplimits')

I do not have your file, so I am stating that this is*_UNTESTED CODE_*. You will have to see if it works.

thanks. it sort of worked in that now there is a date on my graph but it doesn't have an interval of dates. I don't know why but i'm definitely closer to figuring it out now

My pleasure.

See if adding 'keepticks' improves things:

datetick('x','dd-mmm-yyyy HH:MM:SS','keeplimits','keepticks')

[Susan Santiago]

that did it! Thanks for your help!

As always, my pleasure!
