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?

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
