Plotting all the columns of a matrix

Hi,

I want to plot columns of two matrices Z_imag and Z_real in two separate graphs.

I tried to do this code but I wasnt able to:

Z_imag=randi(10,10,3);
Z_real=randi(10,10,3);
width_mil=1:10
for i=1:1:3
figure(1)
Z_im = axes;
plot( Z_im,width_mil,Z_imag(:,i),'-o');
title('Imaginary part of the impedance');
xlabel('W [mil]');
ylabel('Im{Z}');

figure(2)
Z_re = axes;
plot(Z_re,width_mil,Z_real(:,i),'-o');
title('Real part of the impedance');
xlabel('W [mil]');
ylabel('re{Z}');
end

Can you upload your data in a MAT file, so that we can execute your code?

[Vinay Killamsetty]

Thank you, I have added more information to the code

Z_imag=randi(10,10,3);
Z_real=randi(10,10,3);
width_mil=1:10
for i=1:1:3
figure(1)
Z_im = axes;
plot( Z_im,width_mil,Z_imag(:,i),'-o');
title('Imaginary part of the impedance');
xlabel('W [mil]');
ylabel('Im{Z}');
figure(2)
Z_re = axes;
plot(Z_re,width_mil,Z_real(:,i),'-o');
title('Real part of the impedance');
xlabel('W [mil]');
ylabel('re{Z}');
end

Could you help with this edited code

I want to plot columns of two matricesZ_imag and Z_real in two separate graphs.

I assumed, stack bar plot of individual column elements:

matricesZ_imag=rand(4,5);
Z_real=randi(10,4,5)
figure,bar(matricesZ_imag','stacked');
figure,bar(Z_real','stacked');

[Vinay Killamsetty]

Thank you for your answer, But I want to plot continous graphs not bar graphs

Z_imag=randi(10,10,3);
Z_real=randi(10,10,3);
width_mil=1:10
for i=1:1:3
figure(1)
Z_im = axes;
plot( Z_im,width_mil,Z_imag(:,i),'-o');
title('Imaginary part of the impedance');
xlabel('W [mil]');
ylabel('Im{Z}');
figure(2)
Z_re = axes;
plot(Z_re,width_mil,Z_real(:,i),'-o');
title('Real part of the impedance');
xlabel('W [mil]');
ylabel('re{Z}');
end

I have added the required data to the code. Could you help me to plot

[KALYAN ACHARJYA]

Suppose you have the following matrix (example)

>> mat=randi(5,2,3)
mat =

     3     3     1
     4     2     1

Can you show the expected result from above matrix? Use paint or any image drawing tool.

[KALYAN ACHARJYA]

mat=[3 3 1;4 2 1];
plot(mat);
% Set the axies levels accordingly (as per your requirements)

I hope, now you can plot two figure for two different matrices, use figure.

[Vinay Killamsetty]

Thank you very much I want other vector "width_mil" as x axis

So i want to plot the arrays Z_real and Z_imag vs width_mil

[KALYAN ACHARJYA]

Suppose

Z_real=[3 3 1;4 2 1];

width_mil=??? % Simple Example, result expected??

Just focus on one graph, Z_real vs width_mil, you can easily replicate the same for other Z_imag vs width_mil

[Vinay Killamsetty]

Sorry for not making my question clear.

Z_real=[3 3 1;4 2 1;2 1 3];

width_mil=[4,8,12]; I have plotted below the example plot for the arrays I have selected

[KALYAN ACHARJYA]

Z_real=[3 3 1;4 2 1;2 1 3]
width_mil=[4,8,12]
plot(width_mil,Z_real);
axis([0,12,0,4])

I hope, your question has been answered!

[Vinay Killamsetty]

Thank you ver much for your solution. It works

[KALYAN ACHARJYA]

Its my pleasure, Vinay!

No loops needed:

plot(mat)
axis([0,5,0,5])

[KALYAN ACHARJYA]

Yes @Madhan +1 Thanks
