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
