graduate

Pretty axis graduations

Syntax

[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();
subplot(1,2,1)
plot2d(y)

subplot(1,2,2)
[ymn,ymx,np] = graduate(min(y), max(y))
rect = [1, ymn, prod(size(y)),ymx];
plot2d([], y, 1,'011',' ',rect,[10,3,10,np])
