graduate

Pretty axis graduations

Calling Sequence

[xi,xa,np]=graduate( xmi, xma,n1,n2)
[xi,xa,np]=graduate( xmi, xma)

Arguments

:xmi,xma real scalars : :n1, n2 integers with default values 3,10 : :xi, xa real scalars : :np integer :

Description

graduate looks for the minimum interval [xi,xa] and a number of tics np such that:

xi <= xmi <= xma <= xa

xa - xi / np = k(10^n), k in [1 3 5] for an integer n

n1 < np < n2

Examples

y=(0:0.33:145.78)';
`clf`_();
`plot2d1`_('enn',0,y)
[ymn,ymx,np]=graduate(`min`_(y),`max`_(y))
rect=[1,ymn,`prod`_(`size`_(y)),ymx];
`clf`_();
`plot2d1`_('enn',0,y,1,'011',' ',rect,[10,3,10,np])
