how to change color line of mutiple result line plot in one graph.I want to differentiate frequency result into 3 different colour.Thank you
%% Import data from spreadsheet
% Script for importing data from the following spreadsheet:
%


%    Workbook: C:\Users\USER\Desktop\clay 2.xlsx Worksheet: xyToExcel
%
% To extend the code for use with different selected data or a different
% spreadsheet, generate a function instead of a script.

%% Import the data
clay2 = xlsread('C:\Users\USER\Desktop\clay 2.xlsx','xyToExcel');
%% Clear temporary variables

clearvars raw;
%% Allocate imported array to column variable names
Time = [clay2(:,1); clay2(:,3);clay2(:,5)];
Acceralation = [clay2(:,2); clay2(:,4);clay2(:,6)];
%% Clear temporary variables
clearvars data raw;
figure(1)
%Acceleration vs Time
subplot(2,1,1);
plot(Time,Acceralation); 
title('Time Domain')
xlabel('Time (s)')
ylabel('Acceleration')
%Frequency Domain
L = length(Time);      % Signal length
n = 2^nextpow2(L); %
Y = fft(Acceralation,n); %Convert acceleration to freq domain
subplot(2,1,2);
plot(1:n,abs(Y));
title('Frequency Domain')
xlabel('Frequency (f)')
ylabel('|(Amplitude)|')

Demo example: 
x = 1:100 ;
y = rand(size(x)) ; 
figure
hold on
plot(x(x<=25),y(x<=25),'r')
plot(x(x>25 & x <=50),y(x>25 & x <= 50),'b')
plot(x(x>50),y(x>50),'g')
