Plot and scale very small numbers
显示 更早的评论
Hi all,
I am interested in ploting the following y-axis (from 10^-16 to 10^-11) in Matlab:
I use the following codes, but I did not get the nicely spaced y-axis as above. What changes should I amend to the codes to get the above y-axis for my y-data?
figure
plot(x,y,'o','r')
ylim([10^-17 10^-10])
yticks([10^-16 10^-15 10^-14 10^-13 10^-12 10^-11])
Thank you for your suggestions.

You need to make the yscale log.
figure;
h = axes;
h.YScale = 'log'; % <------- or set(h, 'YScale', 'log')
ylim([10^-17 10^-10])
yticks([10^-16 10^-15 10^-14 10^-13 10^-12 10^-11]) % (not needed)

Hi Adam ,
I am unable to implement your code in my machine. Is there any alternative to it?

Why are you unable to implement this? What release are you using?
Another way to get a linear X axis and a logarithmic Y axis is to use semilogy.
x = 1:6;
y = 10.^-(10+x);
semilogy(x, y)
