This attribute controls the appearance of an annotated
coordinate grid (drawn with the astGrid function) by determining
whether the numerical axis labels should be in normal decimal form
or should be represented as 10 raised to the appropriate power.
That is, an axis value of 1000.0 will be drawn as "1000.0" if
LogLabel is zero, but as "103" if LogLabel is non-zero. If
graphical escape sequences are supported (see attribute Escape),
the power in such exponential labels will be drawn as a small
superscript instead of using a "" character to represent
The default is to produce exponential labels if the major tick
marks are logarithmically spaced (see the LogTicks attribute).
