Plotting five figures from one 7 x 20 matrix

Hi, I am having trouble with plotting five figures from one 7 by 20 matrix, where the first four columns denote the x coordinates of the four lines of the first figure, the second four columns denote the x coordinates of the four lines of the secong figure, etc. I have tried something as follows:

pstar = cell2mat(pStar);

N2 = 5;

for i5 = 0:N2:((N2*N2)-1)

pstar1 = pstar(:,i5+1);

pstar2 = pstar(:,i5+2);

pstar3 = pstar(:,i5+3);

pstar4 = pstar(:,i5+4);

end

which would give me a figure on using:

% pStar plot

figure(3)

plot(pstar1,X1,'+')

hold on

plot(pstar2,X1,'+')

plot(pstar3,X1,'+')

plot(pstar4,X1,'+')

hold off

title('Radial Distribution of Dimensionless Pressure')

xlabel('p*')

ylabel('x')

legend('{C}_{{w}_{1}}','{C}_{{w}_{2}}','{C}_{{w}_{3}}','{C}_{{w}_{4}}')

grid

where the y coordinates are: X1 = 0.4000 0.5000 0.6000 0.7000 0.8000 0.9000 1.0000 , corresponding to each of the seven rows, and the matrix:

Something like this?

X1 =  [0.4000    0.5000    0.6000    0.7000    0.8000    0.9000    1.0000];

Exactly that, thank you!
