How to draw multi plots with same x axis and different ranged y axis in a same figure? (See the x axis and y axis values written in the image attached) .
clc;
close all;
t=0:0.000001:0.1;
x=sin(100*t);
y=cos(100*t);
plot(t,x);
hold on
plot(t,y);

Hi Reji,
You can use subplot function to create axes in tiled positions which might be useful for your case.
However, If you need something similar to what you draw in your attachment, you can trick figure to add some offset to one of your arrays and change y axes labels to appropriate strings. Check the following code block:
clc
clear
close all;
t = 0:0.000001:0.1;
x = sin(100*t);
y = cos(100*t);
y = y + 3; % Offset
figure
plot(t,x);
hold on
grid on
plot(t,y);
yTickLabels = string([-1 -0.5 0 0.5 1 0 -1 -0.5 0 0.5 1]);
set(gca, 'yticklabel', yTickLabels)
Good luck

How to hide the center(1 0 -1)ticklabels alone ?

You can achieve the desired outcome using subplot function as below:
t=0:0.000001:0.1;
x=sin(100*t);
y=cos(100*t);
figure;
subplot(2, 1, 1); % First subplot
plot(t, x);
ylim([-1 1]);
title('Plot 1');
subplot(2, 1, 2); % First subplot
plot(t, y);
ylim([-1 1]);
title('Plot 2');

Thank you for the response. Subplot/tiledlayout will create plots in individual boxes. But I need multi plots in One box. Please see my hand sketch.
