How to change the color of my plots

Hello everone,

I've plot my figure in matlab as follows

close all
clear all
avalues=0.3:0.01:1;
N=8000;
d=0.03;
a=avalues;
x=0.78;
y=0.81;
X=zeros(N,length(a));
Y=zeros(N,length(a));
for n=1:0.3*N
    x=(1-d).*x.*exp(a.*(1-x).*((x/0.2)-1))+d.*y.*exp(a.*(1-y).*((y/0.2)-1));
    y=(1-d).*y.*exp(a.*(1-y).*((y/0.2)-1))+d.*x.*exp(a.*(1-x).*((x/0.2)-1));
    X(n,:)=x;
    Y(n,:)=y;
end

figure (9), hold on 
for n=.3*N:N
    x=(1-d).*x.*exp(a.*(1-x).*((x/0.2)-1))+d.*y.*exp(a.*(1-y).*((y/0.2)-1));
    y=(1-d).*y.*exp(a.*(1-y).*((y/0.2)-1))+d.*x.*exp(a.*(1-x).*((x/0.2)-1));
    X(n,:)=x;
    Y(n,:)=y;
    plot(a,x,'.','MarkerSize',0.01)
    hold on
    plot(a,y,'.','MarkerSize',0.01)
    axis([0.3 1 -1 1.4])
end
hold off

The output is

As we can seen, I have two figures on each other.

How can I change its color to the colors something like this?

Just put the color code for the markers. May try the following:

for n=.3*N:N
    x=(1-d).*x.*exp(a.*(1-x).*((x/0.2)-1))+d.*y.*exp(a.*(1-y).*((y/0.2)-1));
    y=(1-d).*y.*exp(a.*(1-y).*((y/0.2)-1))+d.*x.*exp(a.*(1-x).*((x/0.2)-1));
    X(n,:)=x;
    Y(n,:)=y;
    plot(a,x,'r.','MarkerSize',0.01)
    hold on
    plot(a,y,'b.','MarkerSize',0.01)
    axis([0.3 1 -1 1.4])
end

hello

I modified a bit your code to get this result :

.code :

close all
clear all
avalues=0.3:0.005:1;
N=200;
d=0.03;
a=avalues;
x=0.78;
y=0.81;
X=zeros(N,length(a));
Y=zeros(N,length(a));
for n=1:0.3*N
    x=(1-d).*x.*exp(a.*(1-x).*((x/0.2)-1))+d.*y.*exp(a.*(1-y).*((y/0.2)-1));
    y=(1-d).*y.*exp(a.*(1-y).*((y/0.2)-1))+d.*x.*exp(a.*(1-x).*((x/0.2)-1));
    X(n,:)=x;
    Y(n,:)=y;
end
figure (9), hold on 
for n=.3*N:N
    x=(1-d).*x.*exp(a.*(1-x).*((x/0.2)-1))+d.*y.*exp(a.*(1-y).*((y/0.2)-1));
    y=(1-d).*y.*exp(a.*(1-y).*((y/0.2)-1))+d.*x.*exp(a.*(1-x).*((x/0.2)-1));
    X(n,:)=x;
    Y(n,:)=y;
    plot(a,x,'r.','MarkerSize',15)
    hold on
    plot(a,y,'b.','MarkerSize',15)
end
axis([0.3 1 0 1.5])
hold off
