Name

axis — Sets ot gets the axis limits of a 2D or 3D graph

vect = axis(value)

value: string or 1 by n vector, n=4 or n=6
vect: 4-vector [XMIN XMAX YMIN YMAX] or 6-vector [XMIN XMAX YMIN YMAX ZMIN ZMAX]

To get the axis limits, use the syntax : AX=axis()

To set the axis limits, use the property 'axis' in a plot command e.g. plot(X,Y,'axis',value) or after a plot use the syntax axis(value)

Value can be :

a 4-vector [XMIN XMAX YMIN YMAX] or 6-vector [XMIN XMAX YMIN YMAX ZMIN ZMAX] then the plot limits are fixed to the given limits.
a string
The allowed strings are Common 2D/3D values
- 'equal' (isometric scale)
- 'off' (no axis is drawn)
- 'box' (a box enclosing the plot without ticks
- 'tight' (he graph fits tightly the axis limits)
- 'left' (the y axis is displayed on the left)
- 'right' (the y axis is displayed on the right)
- 'center' (the x and y axis cross at the center of the plot box)

t=linspace(0,2*%pi,63);
plot(cos(t),sin(t),'axis','equal');
plot(cos(t),sin(t));
axis([0 1 0 1]);
