How to reset symbol options to their defaults?

Werner Geiger
Posted 1 year ago

As an example I use Graphics3D:

Graphics3D[Cone[]]

enter image description here

If I set some options for following function calls: 

SetOptions[Graphics3D, Axes -> True, AxesLabel -> {x, y, z}, FaceGrids -> All,
   Background -> Lighter[Gray, 0.9], ImageSize -> Small];
Graphics3D[Cone[]]

enter image description here

... How can I return to the default options later?

Do I really have to set every single option again, to its default value? Then I have to know all those defaults:

SetOptions[Graphics3D, Axes -> False, AxesLabel -> None, FaceGrids -> None, 
  Background -> None, ImageSize -> Automatic];
Graphics3D[Cone[]]

enter image description here

Or is there a way to reset all options to default values for each symbol? Of course, without knowing the default values.

Thanks Hans, this methods seems even better than SetOptions since it doesn't affect all Graphics3D but only those where the sequence is explicitly used.

Thanks Henrik & Eric, this solutions do exactly what I asked for.

Another approach is to collect your custom option values in a named Sequence

myGraphics3DOptions=Sequence[
  Axes->True,AxesLabel->{x,y,z},FaceGrids->All,Background->Lighter[Gray,0.9],ImageSize->Small
];

Graphics3D[Cone[], myGraphics3DOptions]

DefaultValues[Graphics3D]

Will give you all default values, including options. You can just extract the default options, but a safer way might be like this:

Lookup[DefaultValues[Graphics3D], HoldPattern[Options[Graphics3D]]]

So, resetting to defaults could look something like this:

SetOptions[Graphics3D, Lookup[DefaultValues[Graphics3D], HoldPattern[Options[Graphics3D]]]]

You could also save the options in a variable before you set your own values, and then you'd reset them back to what you saved when you're done.

Werner,

I would simply save the respective original options at the beginning, i.e. doing it like so:

origGrOpts = AbsoluteOptions[Graphics3D[]];
Graphics3D[Cone[]]
SetOptions[Graphics3D, Axes -> True, AxesLabel -> {x, y, z}, FaceGrids -> All, Background -> Lighter[Gray, 0.9], ImageSize -> Small];
Graphics3D[Cone[]]
SetOptions[Graphics3D, origGrOpts];
Graphics3D[Cone[]]
