How i can change the x-axis labels and ticks like that

Hello , i have been trying to change my code to get the xticks and xlabels in this image but i dont know what to do

Here is the picture

and here is my picture with the code below it

clc
clear all
close all
 
dataset = xlsread('Final2.xlsx','Sheet1','C1:D121')
hour = dataset(:,1)
kp = [dataset(:,2)]
 
 
t=linspace(0,24,120)
subplot(5,1,1)
bar(hour,kp)
ylabel  'kp index'
 
grid on
 
xticks ([0:4:120])
xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
 
data = xlsread('Final2.xlsx','Sheet2','D2:I7201')
mins = data(:,1)
Bz = data(:,2)
subplot(5,1,2)
plot(mins,Bz)
 
 
%xticks ([s])
%xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
ylabel  'Bz(nT)'
 
 
Vx= data(:,3)
subplot(5,1,3)
plot(mins,Vx)
 
ylabel  'Vx Km\s'
 
 
Al = data(:,4)
Au = data(:,5)
subplot(5,1,4)
hold on 
plot(mins,Au)
plot(mins,Al)
ylabel 'AU & AL(nT)'
 
SYM = data(:,6)
subplot(5,1,5)
plot(mins,SYM)
ylabel 'SYM-H(nT)'
xlabel  'UT(hr)'
%xticks(0:4:120)
%xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
 
how i can change the xlabels and xticks to be   '0','4','8','12','16','20','24' and repeat itself

If you're using Matlab r2019b or later, you can use tiledlayout() to create your subplots (see examples in that link).

For earlier releases, you can use linkaxes() to set equal axis limits between all subplots. You'll need the axis handles which would look something like this

sbp(1) = subplot(5,1,1); 
% Your code
sbp(2) = subplot(5,1,2); 
% Your code
sbp(3) = subplot(5,1,3); 
% Your code etc.....

% Then, after all subplots are created, 
linkaxes(sbp, 'x')

[Adam Danz]

Upon closer look at your code, I see that you are using hour as x-values in the first subplot and mins as x-values in all other subplots. Here are some options

1. Use a different xlim() and xtick for the hours data.
2. Convert your hours data to mins
3. a combination of 1 and 2 above where your xticklabels differ from your xticks

Do you see what I mean?

i understand step 1 and step 2 but i dont get step 3 can you explain furthermore ?

[Adam Danz]

Those are 3 different options or ideas, not 3 steps.

I actually don't recommend option 3. Options 1 and 2 are much cleaner and easier.

Here's an example of option 3. The x axis values are actually 1,2,3,4,5 but I've altering their labels to appear as 10,20,30,40,50. If you add a new value at x=40, you won't see it because it will be way off the figure.

figure()
x = [1 2 3 4 5]; 
y = [1 3 14 29 48]; 
plot(x,y, 'o')
set(gca, 'XTick', 1:5, 'XTickLabel', {'10' '20' '30' '40' '50'})

Thanks Adam , last answer worked for me

Answer 2

[samer hisham]

Well i dont think it worked for me , or i typed it wrong

clc
clear all
close all
 
dataset = xlsread('Final2.xlsx','Sheet1','C1:D121')
hour = dataset(:,1)
kp = [dataset(:,2)]
 
 
t=linspace(0,24,120)

sbp(1)= subplot(5,1,1)
bar(hour,kp)
ylabel  'kp index'
 
grid on
 
xticks ([0:4:120])
xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
 
data = xlsread('Final2.xlsx','Sheet2','D2:I7201')
mins = data(:,1)
Bz = data(:,2)
sbp(2)=subplot(5,1,2)
plot(mins,Bz)

%xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
ylabel  'Bz(nT)'
 
 
Vx= data(:,3)
sbp(3)=subplot(5,1,3)

ylabel  'Vx Km\s'

linkaxes(sbp, 'x')
