Thread Subject: help! question about plot

I have some data, t=[1,2,....10^6], y=[.......]
I want to plot y~t, it is simple, my problem is, because I
am more interested in t=[1,10^4], in the interval t=[10^4,
10^6], y value does not change too much, so, I want to plot
y~t, interval t=[1,10^4] with scale 100, and interval t=
[10^4,10^6] with scale 10^4, and they are in the same plot
just with different scale. I really have no idea. thanks a
lot!!!

one of the copious solutions

% the data
     t=1:10; % let's be a bit more modest...
     y=rand(size(t));
     e1=1:4; % epoch 1
     e2=6:10; % epoch 2: note gap
% the engine
     line(t(e1),-1+.1*y(e1),...
         'marker','o','color',[1,0,0]);
     line(t(e2),1+2*y(e2),...
         'marker','s','color',[0,1,0]);

It still does not solve this problem,

Maybe "plotyy" would be of some help to you.

well, why not?!
would you mind being a bit more specific...
your rant - just by itself - is useless...

Hi us
  I mean,
 Because, these two lines still have the same scales on the
xaxis, for example, in your plot, I hope, the red line is
in the range [1,4], the green one is in [10,100], and they
have different scales, and I hope the red line in [1,4] is
not compressed. that is, in your plot, we change nothing,
just replace 6,7,8,9,10 with [60,100], and the plot looks
the same, that is what I need. thank you!
