how to plot like the following figure( i need code)

[dpb]

That would take only about 4-5 lines...

1. Read the data (importdata, readtable, readmatrix, ...)
2. plot data by column w/ X-axis column of the desired variable
3. call xlabel(), ylabel()
4. legend()

Give it a go...we can't do anything specific w/o knowing where the data are and in what form...

[Faizullah khan]

The data is in the following form dear Sir

Legends will be A F M B C Proposed

Hi Faizullah:

You need to get the coordinates of each data, for example, in the green curve (TSMF) the data are : (5,50),(10,100),(20,250) ... so on and so forth. Remeber each point has the coordinate (x,y).

points_coords = [5 50;10 100;20 250;30 650;40 1500;50 3500]; % is a matrix of 6x2 
x = points_coords(:,1);             % the colon symbol in the firs potition selects every row, and the "1" the first column
y1 = points_coords(:,2);
plot(x,y1,'g-^')                    % the 'g-^' g = green (color) - = solid line (line type) ^ = generates triangles (marker)

As you can see is only a curve. You need to add the corresponding points within the points_coords varibale and generates new variables y2, y3 .... yn. For more information about the parameters to plot the other curves visit the plot function documentation. You can olso visit: xlabe, ylabel, title and legend commands.

Regards!

Dear sir

still giving one curve.

you may check my code as under

points_coords = [5 50;10 100;20 250;30 650;40 1500;50 3500]; % is a matrix of 6x2

x = points_coords(:,1); % the colon symbol in the firs potition selects every row, and the "1" the first column

y1 = points_coords(:,2);

plot(x,y1,'g-^') % the 'g-^' g = green (color) - = solid line (line type) ^ = generates triangles (marker)

points_coords = [5 500;10 1000;20 350;30 550;40 1200;50 3000]; % is a matrix of 6x2

y2 = points_coords(:,2);

plot(x,y2,'r-^')

Andrés Castro Sir done. My problem solved with the help of your script.

Thank you very much

kind Regards

Yes, that's right. But now we have the data is more easier.

x = 10:10:90            % the colon operator allows define a vector on a range with increments initial:increment:final
MSE_values = [5.9392, 7.3934, 10.2113, 13.6319, 17.0441, 21.9598, 28.1901, 35.3217, 47.1861;
              15.3395, 32.8796, 48.0746, 75.7206, 117.3670, 152.2416, 220.0498, 262.7240, 357.6435]
y = MSE_values'; % the ' symbol carries out the transpose of a matrix (is to say, change rows by columns and columns by rows)
hold on         % hold on comand allows plot multiplecurves at the same time  
grid on         % grid on comand shows the grid over the plot
plot(x, y(:,1),'b-o');  % plot the A curve in color blue and marker o in a solid line
plot(x, y(:,2),'g-^');  % plot the F curve  in color green and marker triangle in a solid line
legend ('A','F') % add legend at the plot

The code above produces:

x =

10 20 30 40 50 60 70 80 90

MSE_values =

5.9392 7.3934 10.2113 13.6319 17.0441 21.9598 28.1901 35.3217 47.1861

15.3395 32.8796 48.0746 75.7206 117.3670 152.2416 220.0498 262.7240 357.6435

y =

5.9392 15.3395

7.3934 32.8796

10.2113 48.0746

13.6319 75.7206

17.0441 117.3670

21.9598 152.2416

28.1901 220.0498

35.3217 262.7240

47.1861 357.6435

Now you have to add the missing values over the MSE_values matrix, then add more plot function for the other curves, for example

plot(x,y(:,3));
plot(x,y(:,4));
.
.
. 
plot(x,y(:,n))

Finally change the legend comand adding the names of the missing cuvers.

Thank you very much Andrés Castro Sir .
