*Logarithmic Scale* - Display Original Values or the Logarithm Thereof

TARGET
======
Chart2 Reimplementation
This feature request should be integrated into the "Scales and Intervals
Specification" 
(http://specs.openoffice.org/chart/Chart_Scales_and_Intervals.odt)

DESCRIPTION
===========
When using the logarithmic scale, most often one wishes to display the original
values. However, there are situations when the logarithm is more useful.

REASON
======
The logarithmic scale is sometimes used to display wide variations in the values
to be displayed. Such variations may be wide enough to preclude efficient
annotation of the graph. Therefore, the logarithm thereof may be more suitable.
E.g., instead of 1 to 1,000,000,000 one may use 0 to 9.

Sometimes, one wishes to highlight the change in the value, so the logarithm is
more useful (a difference of 1 logarithm step means a change by a factor 10).
This is especially useful in virology (viral load) and in serology (log2).

Some adimensional data or data with non-relevant dimensions may be better
represented by the logarithm, then by the original value. See also e.g. the
following free articles where such graphs occur:
http://www.nature.com/hdy/journal/v93/n6/pdf/6800559a.pdf and
http://www.jneurosci.org/cgi/reprint/25/43/10049 .

IMPELEMNTATION
==============
1. checkbox: display original value (checked by default)
2. checkbox: display the log
