options - How can I work out which functions work with SetOptions?


Not all functions seem to work with SetOptions. e.g.


SetOptions[Grid, BaseStyle -> Directive[Red]];
Grid[{{"hello", "world"}}]

hello world


the font is not red.


SetOptions[Row, BaseStyle -> Directive[Red]];
Row[{"hello", "world"}]

hello world

...and the font is red.


enter image description here


SetOptions[InputField, FieldSize -> 5];

InputField[Dynamic[x]]

the input field size is much larger than 5. But on the other hand


InputField[Dynamic[x], Sequence @@ Options[InputField]]

yields an input field with field size 5.


enter image description here


...and so on.


What is the easiest way to work out (i.e. make a list of ...) which functions can't be used with SetOptions?



Answer




As noted in the question, when you set an option to a function which appears not to work with SetOptions the options do get set, e.g. from the question:


InputField[Dynamic[x], Sequence @@ Options[InputField]]

but for whatever reason the global setting does not get used locally by default.


Another interesting case is this:


SetOptions[Grid, Background -> RGBColor[1, 0, 0]]

which returns a list of Grid options with the new Background, yet when you do the same with GridBox


SetOptions[GridBox, Background -> RGBColor[1, 0, 0]]
SetOptions::nspt: "SetOptions of GridBox is not supported"


So testing the actual "box form" seems to highlight the problem. In this case GridBox is not supported for SetOptions even though Grid did not return an error. So the following solution is a variation of what was provided to me by tech support. Check can be used to return something in the case of a SetOptions error:


Check[SetOptions[GridBox, "a" -> "b"], err, SetOptions::nspt]

SetOptions::nspt: "SetOptions of GridBox is not supported."
err

First get a list of names:


names = Names["System`*"]


test the names for the SetOptions error


list = Quiet[Map[Check[SetOptions[ToExpression[#], "a" -> "b"]; Null, #, 
      SetOptions::nspt] &, names]];

delete the Null elements


DeleteCases[list, Null]

{ActionMenuBox,AnimatorBox,CheckboxBox,ColorSetterBox,CounterBox,DynamicBox,
DynamicModuleBox,DynamicWrapperBox,GridBox,InputFieldBox,ItemBox,Line3DBox,LineBox,
LocatorBox,LocatorPaneBox,OpenerBox,OptionValueBox,OverlayBox,PaneBox,PanelBox,

PaneSelectorBox,Point3DBox,PointBox,PopupMenuBox,ProgressIndicatorBox,RadioButtonBox,
RectangleBox,RotationBox,SetterBox,Slider2DBox,SliderBox,TabViewBox,TemplateBox,
TogglerBox,TooltipBox,ValueBox}

So we have a list of 36 types of boxes that cannot be used with SetOptions.

plotting - Filling between two spheres in SphericalPlot3D

Manipulate[ SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, Mesh -> None, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], {n, 0, 1}] I cant' seem to be able to make a filling between two spheres. I've already tried the obvious Filling -> {1 -> {2}} but Mathematica doesn't seem to like that option. Is there any easy way around this or ... Answer There is no built-in filling in SphericalPlot3D . One option is to use ParametricPlot3D to draw the surfaces between the two shells: Manipulate[ Show[SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], ParametricPlot3D[{ r {Sin[t] Cos[1.5 Pi], Sin[t] Sin[1.5 Pi], Cos[t]}, r {Sin[t] Cos[0 Pi], Sin[t] Sin[0 Pi], Cos[t]}}, {r, 1, 2 - n}, {t, 0, Pi}, PlotStyle -> Yellow, Mesh -> {2, 15}]], {n, 0, 1}]

plotting - Plot 4D data with color as 4th dimension

I have a list of 4D data (x position, y position, amplitude, wavelength). I want to plot x, y, and amplitude on a 3D plot and have the color of the points correspond to the wavelength. I have seen many examples using functions to define color but my wavelength cannot be expressed by an analytic function. Is there a simple way to do this? Answer Here a another possible way to visualize 4D data: data = Flatten[Table[{x, y, x^2 + y^2, Sin[x - y]}, {x, -Pi, Pi,Pi/10}, {y,-Pi,Pi, Pi/10}], 1]; You can use the function Point along with VertexColors . Now the points are places using the first three elements and the color is determined by the fourth. In this case I used Hue, but you can use whatever you prefer. Graphics3D[ Point[data[[All, 1 ;; 3]], VertexColors -> Hue /@ data[[All, 4]]], Axes -> True, BoxRatios -> {1, 1, 1/GoldenRatio}]

plotting - Adding a thick curve to a regionplot

Suppose we have the following simple RegionPlot: f[x_] := 1 - x^2 g[x_] := 1 - 0.5 x^2 RegionPlot[{y < f[x], f[x] < y < g[x], y > g[x]}, {x, 0, 2}, {y, 0, 2}] Now I'm trying to change the curve defined by $y=g[x]$ into a thick black curve, while leaving all other boundaries in the plot unchanged. I've tried adding the region $y=g[x]$ and playing with the plotstyle, which didn't work, and I've tried BoundaryStyle, which changed all the boundaries in the plot. Now I'm kinda out of ideas... Any help would be appreciated! Answer With f[x_] := 1 - x^2 g[x_] := 1 - 0.5 x^2 You can use Epilog to add the thick line: RegionPlot[{y < f[x], f[x] < y < g[x], y > g[x]}, {x, 0, 2}, {y, 0, 2}, PlotPoints -> 50, Epilog -> (Plot[g[x], {x, 0, 2}, PlotStyle -> {Black, Thick}][[1]]), PlotStyle -> {Directive[Yellow, Opacity[0.4]], Directive[Pink, Opacity[0.4]],
