dynamic - Making ColorSetter work like a PasteButton

I might be missing something obvious here. I am building a palette for constructing code to make certain graphics. The idea is that my colleagues can click buttons instead of having to know the right commands. So PasteButton[] is an obvious help. Where I have gotten stuck is in color definition. What I want is for the user to be able to select a color on a ColorSlider, and then click a button to paste the RGBColor[] value selected in that ColorSlider at the notebook insertion point. I do not want the code pasted in this way to update subsequently when the user chooses a different color in the ColorSlider

This is what I have so far, but the resulting pasted code does not pick up when the user has selected a different color in the slider. Pasting Dynamic[col] instead of Setting[col] results in a piece of code that changes when a different color is selected in the slider, which as I mentioned is not the desired behaviour.

Grid[{{PasteButton[

    Graphics[{Dynamic[col], Rectangle[]}, ImageSize -> 26], 
    Setting@col, ImageSize -> 26, ImageMargins -> 0, FrameMargins -> 0], 
   ColorSlider[Dynamic[col], ImageSize -> {75, 25}, 
   AppearanceElements -> "Spectrum"]}}, Spacings -> 0, Alignment -> Bottom]

enter image description here

The idea is that the user clicks on a color in the spectrum zone, and then clicks the button on the left that looks like a swatch.

How do I modify / rewrite this code to achieve the desired behaviour?

Answer

If you wrap your entire widget (as currently shown in your code), in Dynamic, it will work. The reason is that without it, changes is col are not propagated to PasteButton.

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....
