plotting problem

I have some problem with plotting, the listing is like this:

 for d=1:1:100;

    p=10^(-10);
    a(d)=100*(10^6)*d/(2*(10^8)*12208);
    u_gb(d)=(1-p)/(1+2*a(d)*p);
    x(d)=d;
 end
 plot(x,u_gb);

those u_gb has very small data, its between 0.999999999899181 to 0.999999999899992. if I plot it, we will see straight horizontal line in the graph. Because of that, we can't see that u_gb 's value has changed

How to make this line more tilted or oblique, so that we can see that the data of u_gb is changed

Answer 1

[G A]

try plot(x,1-u_gb,'.k');

It may help to make the data points visible in the graph.

plot(x,u_gb,'.-')

Answer 3

Have you tried just adjusting the y-axis scale?

doc axis

yes, but still, it did't change the graph
