When the following plots are displaying data on the original scale:
this function will be in their right-click menus.
It generates a new plot of the same type as
the one on which it is invoked.
The positive data in the original plot are drawn on a log base 2 scale
in the new plot.
It is only active and not grayed out in a right-click menu
when the variable or variables being displayed have
positive values in a plot.
It is these positive values
that are going to be redrawn on a log base 2 scale.
The following sequence of figures demonstrates this point.

Panel A is a scatterplot.
Applying
Use Log Scale to Panel A
to get the scatterplot in Panel B.
Making all data in Panel B red
to get Panel C.
Now the scatterplot in Panel A
becomes the scatterplot in Panel D
with all first-quadrant points painted red.
