Some new data now:
60
t = linspace(0,1);
40
x = humps(t);
20
y = humps(t.^2)/2;
plot(x,y) 0 0 50 100
The Axes limits have been set to the next round number in the series of
tick marks. To change the scale so that the data fill the whole plot:

40
axis tight 30
20
10
20 40 60 80
To zoom in on the loop:
12
10
axis([10 25 5 12]) 8
6
10 15 20 25
To zoom back out again: 12
60
40
axis auto 20
0
0 50 100
Now let us look at some image data:

clf
load clown 50
100
image(X)
150
colormap(map)
200
100 200 300
The y-axis here increases from top to bottom: the ij axis mode is the
default for images. To get the y-axis increasing from bottom to top:

200
150
axis xy 100
50
100 200 300
To go back again:
12 Or you can use the zoom function, which initiates a mouse-based zoomer.
