how to rotate x-ticklabel for date?

Hello everyone,

In fact, I plotted my data against date using the following code but my x-axis ticklabel are overlaped. So, I am trying to rotate my x-axis ticklabel which is giving an error.

clear all; clc;

fid=fopen('GEM.dat');

data_f1=textscan(fid,'%f %f %f %f %f %f %f %f %f %f %f %f', 'delimiter',':/','collectoutput',1,'headerlines',1);

N = size(data_f1{1},1); % number of rows

t = datenum([data_f1{1}(:,[3 1 2 4 5]) zeros(N,1)]);

A = datestr(t, 'yyyy-mm-dd HH:MM:SS');

C = (data_f1{1}(:,6:11));

plot(t,C(:,1));

xpts = min(t):max(t);

set(gca,'XTick',xpts,'XTickLabel',datestr(xpts));

th=rotateticklabel(gca,45);

% rotateXTickLabel(gca, 45)

close all;

the error is ??? Undefined function or method 'rotateticklabel' for input arguments of type 'double'.

Does any of my friends have any idea how can I get rid of this problem? Thank you very much in advance for helping me.

Did you forget to download the function and put it in a folder that is on your path?

rotateticklabel

Would you please tell me the procedure to do that.

Yes,

1. Click the link I gave above. 2. Look for the Download button, click it, save file. 3. Go to the downloaded files, extract them. 4. Cut and paste the file named rotateticklabel.m to the MATLAB directory.

Try your code again.

Thanks a lot Matt. It did serve the purpose of rotating the x-axis label. But still I have some problem and that is my x-axis label is above the axis that I want below the axis. And the date interval is by one day that I want by fifteen days for a clear view. Any suggestions please? Thanks again

HI¡

Firstly, thanks for the programme. But how could I change the fontsize of the x-axis label? because once I run rotateticklabel.m I can only modify the size by clicking manually in each label.

I hope you can sort this out¡

thanks again
