plotting - How do you put a plot inside a popupmenu that is inside another popupmenu?


I have the next code


 Manipulate[
     Switch[x, a, If[selection =!= None, selection = None], b, 
        If[selection === None, selection = None], c, 
        If[selection === None, selection = "Hola"]

 ];
 selection, {x, {a, b, c}, ControlType -> PopupMenu},  
 {{selection, None}, 
     Switch[x, a, {"recta", "parabola"}, b, {"hiperbola", "absoluto"}, 
     c, {"Seno", "Coseno"}], ControlType -> PopupMenu}
 ]

but I need you to choose the second popupmenu I plot the function chosen.



Answer



Actually, I have to admit I do not quite understand what you are aiming for, so here's a long shot...



I understand that you want to have values in the second control (selection) that do depend on the first control, x that is.


Also, based on the title, I added some plots in the PopupMenu. Looks fun.


I hope it helps in some way. The key issue is that I introduced a helper, called selChoice to keep track of the updated selection-list. selChoice has ControlType None, so you won't see it in the actual Manipulate.


a = "Algebraicas";
b = "Trigonometricas";
c = "Tercer Grado";

Module[{myPlot},
    myPlot[f_] := Plot[f[x], {x, -5, 5}];
    Manipulate[

       Switch[x,
          a, If[selection =!= None, selection = None],
          b, If[selection === None, selection = None],
          c, If[selection === None, selection = "Hola"]];
       selection,
       {x, {a, b, c}, ControlType -> PopupMenu}, 
       {{selection, None}, selChoice, ControlType -> SetterBar},
       {{selChoice,
           Which[x == a, myPlot /@ {# &, #^2 &},
              x == b, myPlot /@ {#^3 &, Abs@# &},

              x == c, myPlot /@ {Sin, Cos}]}, None}]]

Note that I have no clue what you want to do with the first Switch... and also note that I am fully aware that my functions do not quite make sense in the respective categories.


Output:

EDIT


Based on the comment, maybe this is more what you want (I am still not sure)


Module[{myPlot}, myPlot[f_] := Plot[f[x], {x, -5, 5}];
  Manipulate[
    myPlot@selection, 

      {x, {a, b, c}, ControlType -> PopupMenu}, 
      {{selection, None}, selChoice, ControlType -> SetterBar}, 
      {{selChoice, Which[
         x == a, {# &, #^2 &}, 
         x == b, {#^3 &, Abs@# &}, 
         x == c, {Sin, Cos}]}, None}]]

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 - 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 - Mathematica: 3D plot based on combined 2D graphs

I have several sigmoidal fits to 3 different datasets, with mean fit predictions plus the 95% confidence limits (not symmetrical around the mean) and the actual data. I would now like to show these different 2D plots projected in 3D as in but then using proper perspective. In the link here they give some solutions to combine the plots using isometric perspective, but I would like to use proper 3 point perspective. Any thoughts? Also any way to show the mean points per time point for each series plus or minus the standard error on the mean would be cool too, either using points+vertical bars, or using spheres plus tubes. Below are some test data and the fit function I am using. Note that I am working on a logit(proportion) scale and that the final vertical scale is Log10(percentage). (* some test data *) data = Table[Null, {i, 4}]; data[[1]] = {{1, -5.8}, {2, -5.4}, {3, -0.8}, {4, -0.2}, {5, 4.6}, {1, -6.4}, {2, -5.6}, {3, -0.7}, {4, 0.04}, {5, 1.0}, {1, -6.8}, {2, -4.7}, {3, -1....
