SYMLOG applies a modified logarithm scale to the specified or current
axes that handles negative values while maintaining continuity across
zero. The transformation is defined in an article from the journal
Measurement Science and Technology (Webber, 2012):

y = sign(x)*(log10(1+abs(x)/(10^C)))

where the scaling constant C determines the resolution of the data
around zero. The smallest order of magnitude shown on either side of
zero will be 10^ceil(C).
