LGAXS plots a single logarithmic coordinate axis. Complete decades are produced. See also AXIS and LGLIN.
CALL LGAXS (x,y,s,n,al,a,nmin,dx<,ic>)
x,y (R): location starting point of the axis
s (C): axis label string
n (I): number of characters in string
> 0 : label on positive side
< 0 : label on negative side
(100's digit) = 0 : coordinate line, ticks and labels drawn
= 1 : line and ticks only--no labeling
(1000's digit) = 0 : numeric labels paralel to axis line
= 1 : numeric labels orthogonal to axis line
(10000's digit) = 0 : color list ignored
= 1 : color list used
al (R): length of axis
> 0 : axis ticks placed on same side of axis as title
= 0 : no action (return with no plotting)
< 0 : ticks placed on opposite side of axis from title
a (R): angle at which the axis should be plotted
nmin (R): number to be printed at the first axis tick (power of ten)
dx (R): scaling factor in the form dx=(nmax-nmin)/l where
nmax, nmin are the exponent powers at the start
and end of the axis
ic (I): color array (accessed if mag(n)>10000))
ic(1) : color for axis line and ticks
ic(2) : color for numbers
ic(3) : color for axis title
