I need to plot (a vs Ex_nz) and (a vs Ex_ny) for different values of b= 0.1, b=0.2, b=0.3, b-0.4 and b=0.5. How can I plot these on the same figure just like the R in the image attached?

clear all; close all; clc;

x(1)=0;
y(1)=0;
a=1:1:14;
b=0.3;
for i=2:10000
    x(i)=1-1.4*(x(i-1)^2)+y(i-1);
    y(i)=b*x(i-1);
end
%plot(x,y,'.','MarkerSize',2)
%hold on
%xlabel('x')
%ylabel('y')
%title('henon map')

end
    figure
hold on
plot (a,Ex_nz,'o-r')
plot (a,Ey_nz,'s-k')

在 MATLAB Online 中打开

Use yyaxis

https://in.mathworks.com/help/matlab/ref/yyaxis.html

Otherwise:

If you want to generate multiple plots with different values of b, consider b as an array, and acess the individual value of b, by passing index position, say

b =[0.1576    0.9706    0.9572    0.4854    0.8003];
figure,
for j=1:length(b)
%Evauate plot data based on b(j)
........ 
y(i)=b(j)*x(i-1);
........
plot 
hold on
end
