plot a data????

I am trying to plot this table below in the picture

Please check my code and make any correction

A=[

5 99.11 5 412

10 99 5 405.25

15 98.91 5 397.85

20 98.81 5 389.73

25 98.71 5 381.13

30 98.61 5 371.97

];

F = figure;

F.Position = [100 100 800 400];

subplot(1,2,1);

plot(A(:,1),A(:,3),'-bo','linewidth',1.5);grid on;hold on;

plot(A(:,1),A(:,4),'-ro','linewidth',1.5);grid on;

str = {'(A)'};

text(10,80,'A','FontSize',14,'FontWeight','bold')

xlabel('Excess Air','FontWeight','bold');

ylabel('Purity CO2','FontWeight','bold')

legend('1^{st} stage','2^{nd} stage','Location','NorthEast')

subplot(1,2,2);

plot(A(:,1),A(:,2),'-go','linewidth',1.5);grid on;hold on;

plot(A(:,1),A(:,5),'-ko','linewidth',1.5);grid on;

str = {'(B)'};

text(13,.77,'B','FontSize',14,'FontWeight','bold')

xlabel('Excess Air','FontWeight','bold');ylabel('Stage Cut','FontWeight','bold')

legend('Overall','Stage cut','Location','NorthEast')

subplot(1,2,1)

legend("Position", [0.28832,0.31347,0.16722,0.12086])

subplot(1,2,2)

legend("Position", [0.73589,0.33223,0.16556,0.10762])

It appears to run correctly, unless there is a quesiton you are not stating.

There are only 4 columns in ‘A’ so this threw the expected error:

plot(A(:,1),A(:,5),'-ko','linewidth',1.5);grid on;

With that correction, it produces the result here —

A=[
5	99.11		5	412
10	99		5	405.25
15	98.91		5	397.85
20	98.81		5	389.73
25	98.71		5	381.13
30	98.61		5	371.97
];
F = figure;
F.Position = [100 100 800 400];
subplot(1,2,1);
plot(A(:,1),A(:,3),'-bo','linewidth',1.5);grid on;hold on;
plot(A(:,1),A(:,4),'-ro','linewidth',1.5);grid on;
str = {'(A)'};
text(10,80,'A','FontSize',14,'FontWeight','bold')
xlabel('Excess Air','FontWeight','bold');
ylabel('Purity CO2','FontWeight','bold')
legend('1^{st} stage','2^{nd} stage','Location','NorthEast')
subplot(1,2,2);
plot(A(:,1),A(:,2),'-go','linewidth',1.5);grid on;hold on;
plot(A(:,1),A(:,4),'-ko','linewidth',1.5);grid on;
str = {'(B)'};
text(13,.77,'B','FontSize',14,'FontWeight','bold')
xlabel('Excess Air','FontWeight','bold');ylabel('Stage Cut','FontWeight','bold')
legend('Overall','Stage cut','Location','NorthEast')
 
    
subplot(1,2,1)
legend("Position", [0.28832,0.31347,0.16722,0.12086])
subplot(1,2,2)
legend("Position", [0.73589,0.33223,0.16556,0.10762])

Are there any other problems?
