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?
