Hi there, I'm trying to set the limits of an x-axis of dates produced in a function. I have two inputs to the function, 'startdate' and 'enddate' which are entered in yyyymmdd format. i have tried the following code to limit the x-axis:
starty = floor(startdate/10000);
startm = floor(rem(startdate,10000)/100);
startd = rem(startdate,100);
xmin=datenum(datetime(starty,startm,startd));
endy = floor(enddate/10000);
endm = floor(rem(enddate,10000)/100);
endd = rem(enddate,100);
xmax=datenum(datetime(endy,endm,endd));
xlim([xmin xmax]);
but i just can't figure out why it doesn't work?? i get no error messages it just doesn't work? i have queried the x limits of the graph produced and get the following:
>> xlim
ans =
1.0e+05 *
7.2592 7.3542
thanks for any help in advance

Hi Aaron,
here is an example how it works:
% three years:
t = datenum(2012, 1:36, 1)';
plot(t, rand(size(t)))
% makes it easier to read:
datetick x
% let's wait
pause(5);
% and "zoom" in:
xlim([datenum(2013, 1,1), datenum(2014,1,1)])

Hi,
I'm not yet sure what is the problem. You limit the X-axis to the following date range:
>> datestr(1e5 * [7.2592 7.3542])
ans =
02-Jul-1987
05-Jul-2013
So what is it that is not working?

It is not clear at which point you do the xlim. You need to use it after you plot, or you need to set hold on after you xlim if you want to plot after you set xlim
