How to begin axis from another value and make it a 0 point in plot matlab?

Hi,
I have some measurements. On the x label they starts from 0 to 100, but from 23 I can see something change on the plot, so I want to show a plot from 23 to 100, and that is how i do this:
plot(x,y)
axis(23, 100, 0, 40)
let's say that y is from 0 to 40 and i don't want to change it.
But now I want to make 23 a 0, so then the 100 whould be 77- how can I make this?
Thanks

If you want the ticks on your plot to show something other than the real numbers, you can either (a) change the numbers, or (b) manually specify your tick values.
To demonstrate, let me create some fake data:
x = 0:100;
fakedata = x/10;
fakedata(24:end) = sin(fakedata(24:end)-2.3)+2.3;
plot(x, fakedata)
Your two options are to either: change the X-values to something different (recommended):
plot(x-23, fakedata)
xlim([0 77])
Or manually specify your tick values:
plot(x,fakedata)
xlim([23 100]);
xticks(23:10:100);
xticklabels(0:10:77);

1) change the limits
plot(x,y)
xlim([23 100])
2) change the data (not recommended)
plot(x,y-23)
