How to plot this graph on Matlab?

HI GUYS I WOULD LIKE TO PLOT THIS GRAPH ON MATLAB ? CAN ANYONE TELL ME HOW TO DO IT ? THANKS IN ADVANCE

Are you aware that using only upper case letters is considered SHOUTING?

Answer 1

[Image Analyst]

You can use rectangle() to plot the circle and oval.

You can use text() to place text labels on the plot.

THANKS @Image Analyst, BUT I WOULD LIKE TO KNOW HOW TO ADD LINE 1 PARAMETER AND LINE 2 PAPAMETER. TEXT IS NOT IMPORTANT, CAN YOU PLEASE TELL ME, IS IT POSSIBLE?

[Image Analyst]

Kristen, you just had to modify the examples in the help, like this:

% Initialization steps.
clc;    % Clear the command window.
close all;  % Close all figures (except those of imtool.)
clear;  % Erase all existing variables. Or clearvars if you want.
workspace;  % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 13;
% Define oscillation parameters.
period = 10;
t = linspace(0, 5 * pi, 100);
y = 30 * sin(2 * pi * t / period);
% Define graphics parameters:
rectangleHeight = 0.15;
rectangleWidth = 0.15;
rectangleLowerLeftX1 = 0.0;
rectangleLowerLeftY1 = 0.1;
lineX = 15;
% Set up axes.
grid on;
ylim([-0.150, 0.3]);
xlim([-0.15, 0.25]);
xlabel('X', 'FontSize', 15);
ylabel('Y', 'FontSize', 15);
faceColor = [.95, 1, .95];
axis('equal');
% Start the movement:
% Place a rectangle at the current y location.
r = rectangle('Position', [rectangleLowerLeftX1, rectangleLowerLeftY1, rectangleWidth, rectangleHeight], ...
	'Curvature', [1, 1], ...
	'LineWidth', 3, ...
	'EdgeColor', 'b', ...
	'FaceColor', faceColor);
title('Rectangles and circles and ovals', 'FontSize', 15);

% Do the oval
rectangleHeight = 0.09 * 2;
rectangleWidth = 1.07;
rectangleLowerLeftX1 = -1;
rectangleLowerLeftY1 = -0.09;
r = rectangle('Position', [rectangleLowerLeftX1, rectangleLowerLeftY1, rectangleWidth, rectangleHeight], ...
	'Curvature', 1, ...
	'LineWidth', 3, ...
	'EdgeColor', 'b', ...
	'FaceColor', faceColor);
xlim([-0.15, 0.25]);

This looks pretty close to the figure you posted. Adapt parameters as needed.

What function would you like to do that? I don't believe rectangle(), xlabel(), ylabel(), or title() take a "line1" or "line2" parameter. If you have a line as (x,y) coordinates, you can use plot():

plot(x, y, 'r--', 'LineWidth', 2); % Plot dashed red line.

[Kristen Chappel]

@Image AnalystIT DOESNOT PLOT THE LINE USING ABOVE CODE , FOR EXAMPLE I GIVEN

X= 2;

Y=3;

plot(x, y, 'r--', 'LineWidth', 2); % Plot dashed red line.

THEN IT NOT PLOT ANY LINE , WHY ?

THANKS

[Image Analyst]

Because using -- plots a line between adjacent coordinates. A line has at least two coordinates, but you gave only one, so there can be no line to the next point (which doesn't exist). You can see the point by using a marker:

plot(x, y, 'r.-', 'LineWidth', 2, 'MarkerSize', 25); % Plot dashed red line.

You can plot a line like this:

x = 1 : 10;
y = rand(1, length(x));
plot(x, y, 'r.-', 'LineWidth', 2, 'MarkerSize', 25); % Plot dashed red line.

THANKS @Image Analyst, IS THEIR NY WAYS TO ENTER THE VALUE OF X AND Y MANUALLY ACCORDING TO OUR CHOICE AND THEN BY CONSIDERING THIS OUR POINT PLOT THAT ENTIRE LINE? THANKS

[Kristen Chappel]

SORRY @Image Analyst, NO I AM STILL FACING THE PROBLEM I AM NOT ABLE TO ADD MORE THAN TWO POINT. IS THEIR ANY WAYS TO ENTER THE VALUE OF X AND Y MANUALLY ACCORDING TO OUR CHOICE AND THEN BY CONSIDERING THIS OUR POINT PLOT THAT ENTIRE LINE? THANKS

[Image Analyst]

Experiment around with the input() or inputdlg() function.

[Kristen Chappel]

@Image AnalystI DIDN'T UNDERSTAND CAN YOU PLEASE EXPLAIN IT IN MORE DETAILS?

[Les Beckham]

@Kristen Chappel

In order to plot more than one point on a plot you need to provide more than one data point. You have not explained where the data for 'Line 1' and 'Line 2' is coming from. As soon as you figure out where that data is coming from it will be easy to plot it along with the other shapes that Image Analyst showed you how to plot.

You should not really post repeated requests for help (especially in all caps, please turn off your caps lock, it is usually interpreted as "yelling") when you haven't explained what you really want or, apparently, listened to the previously provided suggestions..

Explain how you want to "ENTER THE VALUE OF X AND Y MANUALLY ACCORDING TO OUR CHOICE". As Image Analyst suggested, you could prompt for them on the command line (using input()) or create a dialog to ask for the values (using inputdlg()). Or, if you want to do it by clicking on the figure you could try ginput().

Read the documentation for those functions. Here are links to the online docs: input, inputdlg, ginput.

Read the examples and come back with specific questions when you have tried something and it didn't work. Also, post the code that isn't working and show any error messages that you get (the complete error message) and explain what you expect and why what you get isn't what you want.
