Contrary to what one might expect, specifying an option to be Automatic
sometimes changes the output. For example, by default Show
's range is set by the first graphic, but setting PlotRange -> Automatic
causes it to choose the best range for all the graphics being shown. Are there any other situations in which Automatic
is not the default option? And is there a way to modify the kind of command given at https://mathematica.stackexchange.com/a/48562/30780 to use the default rather than the Automatic
value?

Show
is a bad example. It actually doesn't have any options with defaults defined for it. A better example isPlotLegends
. For most plotting functions (maybe all?) the default value isNone
, whilePlotLegends -> Automatic
turns on automatically generated legends. $\endgroup$ – m_goldberg Mar 1 '17 at 11:27
