programming - Deploying Mathematica Content Online


I have the following program at home, which draws on a batch of pre-processed files (that are word frequency text files, compiled using ToLowerCase, Tally and Sort. Here is an example of the file that it draws on:


{{"i", 3073}, {"you", 2860}, {"the", 1741}, {"and", 1518}, {"a", 1218}, {"me", 1209}, {"to", 1153}, {"my", 913}, {"t", 855}, {"that", 843}... and so on. Each file is about ~ 50KB, and it's been generated using Put and is thus grabbed using Get.


I use them for the following program, which essentially plots word frequency for a given year (each year has its own file). It's along a similar lines as the Google ngram viewer, but on a very specific historical dataset.



Manipulate[viewerCount1 = {};
 viewerCount2 = {};
 SetDirectory["/users/myNAME/desktop/DB/Put/"];
 filenames = FileNames["*.txt"];
 Do[
  input = Get[file];
  yearLength = Length[input];
  AppendTo[viewerCount1, 
   If[Length[Flatten[Cases[input, {word1, _}]]] == 0, 0, 
     Flatten[Cases[input, {word1, _}]][[2]]]/yearLength];

  AppendTo[viewerCount2, 
   If[Length[Flatten[Cases[input, {word2, _}]]] == 0, 0, 
     Flatten[Cases[input, {word2, _}]][[2]]]/yearLength];
  , {file, filenames}];
 DateListPlot[{Tooltip[viewerCount1, word1], 
   Tooltip[viewerCount2, word2]}, {1964}, Joined -> True, 
  PlotLabel -> "Number of Total Word Appearances by % of All Words", 
  PlotStyle -> {{Red}, {Blue}}], {{word1, "war", 
   "First Word (Red)"}}, {{word2, "peace", "Second Word (Blue)"}}]

Here's the crux of the question, however. Is there a good way to deploy this online so other people can access it? I assume this is too big for the CDF format? Alternatively, WebMathematica sounds promising, but before I upgrade my Mathematica purchase I would love to hear if the community thinks that would be useful.


I know that there have been discussions elsewhere about sharing dynamic content with non-Mathematica users, but these seem to not rely on specific external files.


Or, am I using the wrong language to deploy the final version of this?



Answer



You cannot use CDF for this because you have textual import fields and these are not supported when you embed online. You will just get a big grey box. InputField cannot accept strings (non-numeric) for online CDFs unless you are Wolfram Research and can override it. (I'm guessing you don't want to pay many thousands for CDF Pro.)


You also cannot import and export into an online embedded CDF, not even a Pro CDF (got that first hand from Wolfram). This is for security reasons.


So to create something like you have described using Mathematica and have online, the only possible way to do it, it would seem, is to use webMathematica.

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 - 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.
