Why the increment of plot not working ?

I don;t know where the error is as instead of 6 figures I get 36 figures as its a 2 for loops ,how to combine these 2 varying for loop results into one.I want to plot both the varying i and S values in 6 figures where the code works well when only i is checked and when I add k it goes to 36 ??

A = [125,25];
S(:,1) = [ 160 195 230 90  55  20];
S(:,2)=  [ 25  25  25   25  25 25 ];
 
for i=[57 81 111 58 81 111]
    for k = 1: 1:length(S)
        figure('Position',[392,345,441,421]);
        surf(Data(:,:,i)); shading interp;  view(2); % couldn;t add data as its a big file
        hold on
        plot(S(k,1),S(k,2),'r.'); % sensor
        hold on
        plot(A(1),A(2),'k.') % actuator
        colormap('summer')
        axis square
        xlabel('Length (cm)','fontweight','bold');
        ylabel('Width (cm)','fontweight','bold');
        xlim([0 250])
        ylim([0 250])        
    end    
end

Hello,

You shoul try to put

figure('Position',[392,345,441,421]);
surf(Data(:,:,i)); shading interp;  view(2); % couldn;t add data as its a big file 
hold on

outsite the loop of "k"

Check does it work or not.

Hi Trung

You mean like this ??

A = [125,25];

S (:, 1) = [160 195 230 90 55 20];

S (:, 2) = [25 25 25 25 25 25];

for i = [57 81 111 58 81 111]

for k = 1: 1: length (S)

plot (S (k, 1), S (k, 2), 'r.' ); % sensor

hold on

plot (A (1), A (2), 'k.' ) % actuator

end

figure ( 'position' , [392,345,441,421]);

surf (Data (:,:, i)); shading interp ; view (2); % couldn; t add data as its a big file

hold on

colormap ( 'summer' )

axis square

xlabel ( 'Length (cm)' , 'fontweight' , 'bold' );

ylabel ( 'Width (cm)' , 'fontweight' , 'bold' );

xlim ([0 250])

ylim ([0 250])

end

But still it plots all the values of S in the same figure ,instead of plotting each value of S in each figure

Hello,

I mean you could try like this

for i=[57 81 111 58 81 111]
    figure('Position',[392,345,441,421]);
    surf(Data(:,:,i)); shading interp;  view(2);
    hold on
    for k = 1: 1:length(S)
        plot(S(k,1),S(k,2),'r.'); % sensor
        hold on
        plot(A(1),A(2),'k.') % actuator
    end
    colormap('summer')
    axis square
    xlabel('Length (cm)','fontweight','bold');
    ylabel('Width (cm)','fontweight','bold');
    xlim([0 250])
    ylim([0 250])  
    hold off 
end

Now, it should plot 6 figures with regard to the loop "i".

[Ramesh Bala]

Thanks indeed it plots 6 figures with S,A values.But all the S values are present in all figures.

Can it be possible that with the k loop iteration S(1,1),S(1,2) in figure one and then S(k,1),S(k,2) goes on in another figures till 6 ?

Now it plots all S values in all 6 figures

Hello,

You could you "if" to plot S(1,1) and S(1,2) in figure 1, for example,

for k = 1: 1:length(S)
    if (i == 1)
        plot(S(1,1),S(1,2),'r.'); % sensor
    else
        plot(S(k,1),S(k,2),'r.'); % sensor
    end
    hold on
    plot(A(1),A(2),'k.') % actuator
end

Is it what you want?

[Ramesh Bala]

No , I have added S(1,1) to give an example.But I want S(k,1),S(k,2) in incremental value in the 6 figures

S(1,1),S(1,2) in figure 1

S(2,1),S(2,2) in figure 2

S(3,1),S(3,2) in figure 3 and so on

Now the present code puts all the S in all the figures

[infinity]

Ok, I get your point. So you don't need to use loop "k" and we could use another variable "count" like in this code

count = 0;
for i=[57 81 111 58 81 111]
    figure('Position',[392,345,441,421]);
    surf(Data(:,:,i)); shading interp;  view(2);
    hold on
    
    count = count + 1;
    
    plot(S(count,1),S(count,2),'r.'); % sensor
    
    hold on
    plot(A(1),A(2),'k.') % actuator

    colormap('summer')
    axis square
    xlabel('Length (cm)','fontweight','bold');
    ylabel('Width (cm)','fontweight','bold');
    xlim([0 250])
    ylim([0 250])  
    
    hold off 
end

I hope it may help.

[Ramesh Bala]

yeah it works ! thanks :)
