scatter plot with non-linear axis

Hi together!

I have been trying for a while now to make a certain graph, but just do not succeed :-(

Here is what I need:

A scatter plot, where the y axis is linear scaled: y = [0.7, 0.9] and the x-axis is non-linear scaled: x = [1/128, 1/64, 1/32, 1/16, 1/8, 1/4, 1/2, 1, 2]

Could anybody PLEASE help me??

x=1:10
y=sin(x)
x1=1./2.^(-1:length(x)-2),
scatter(x1,y)

Thank you Azzi for your answer! However it doesn't work for me. :-( when I copy your code I still get a linearly scaled axis??

[Azzi Abdelmalek]

I am not getting this message, are you sur you din'nt do anything else

[Birgit]

yes, I am sure I didn't do anything else. I copied it 1:1 and I get a linearly scaled axis

[Azzi Abdelmalek]

try this

close
x=1:10
y=sin(x)
x1=1./2.^(-1:length(x)-2),
scatter(x,y)
set(gca,'xticklabel',fliplr(x1))
grid

set(gca, 'XScale', 'log')

This will give you log 10, but log 2 is a linear multiple of log 10.

thanks to both of you! :-) it's great to get help here!
