Automated export to interactive HTML

We got rid of a hassle, that you needed to do in order to export notebooks with interactive elements. At least for the build-in functions such as:

%3Cbr%20%2F%3E
  • Manipulate
  • ManipulatePlot
  • ManipulateParametericPlot
  • Animate

this is a single click - Automatic

Here Manual sampling is the same, as Dynamic HTML option was before.

Try it out!

Manipulate[Plot3D[Sin[x w]Cos[y w], {y,0,2Pi}, {x,0,2Pi}, PlotRange->Full, ColorFunction->"Rainbow"], {w,0.1,2,0.1}, ContinuousAction->True]

Manipulate and Animate

We improved our JIT transpiler. But it might still not like too many changes.

Try to keep the number of curves/traces the same as well as polygons if possible to get the most from JIT. Try not to add new entities as well.

PerformanceGoal->"Speed" is also a good option for 3D plots.

Mesh->None might also help.

PlotRange->Full can help to avoid fragmentation of line segments

Here is some more examples:

Manipulate[
 Plot[Evaluate[
   y[t] /. First[
     NDSolve[ {y''[x]  -x y[x], y[0]  a, y'[0] == b}, 
      y, {x, 0, 4}]]], {t, 0, 4}, 
  Epilog -> {Point[{4, 1/2}], Green, Arrow[{{0, a}, {1, b + a}}], Red,
     Point[{0, a}]}, ImagePadding -> 25, PlotRange -> {{0,4.5}, 2{-3,3}}],
 {{a, 1}, -3, 3, 0.5},
 {{b, 0}, -3, 3, 0.5}, ContinuousAction->True
]

Animate

Plot expression with epilog

Animate[Plot[1.0 + Sin[w] Sin[x + w],{x,0,5Pi}, Epilog->{
  Red, Point[{8.0, 1.0 + Sin[w] Sin[8.0 + w]}]
}], {w,0,Pi}]

In any case, please, consider to use ManipulatePlot or general low-level building blocks like Offload and etc for more complex cases.

Images are also supported:

img = ImageResize[ExampleData[{"TestImage","Apples"}], 500];
Manipulate[ImageAdjust[img, i], {i,-1,1,0.3}, ContinuousAction->True]

Improved Shell Cells

We switched to StartProcess for shell-like cells:

%3Cbr%20%2F%3E

It allows running something continuously without blocking the kernel. To interrupt the process - simply abort the evaluation as usual.

Improved Labels for Graphics

We fixed a couple of bugs related to label positioning and font rendering. Here is an example:

ListPlot[MapThread[Labeled, {{{1,2},{2,4},{4,6}}, {"1","2","3"}}]]
(*VB[*)(FrontEndRef["2c568e52-2973-432d-a871-f6e70ccd1dfc"])(*,*)(*"1:eJxTTMoPSmNkYGAoZgESHvk5KRCeEJBwK8rPK3HNS3GtSE0uLUlMykkNVgEKGyWbmlmkmhrpGlmaG+uaGBul6CZamBvqppmlmhskJ6cYpqQlAwB39xWq"*)(*]VB*)

and for Offset, you can specify the displacement of labels or set an absolute size for Disk, Circle and others:

Plot[x, {x,0,1}, Epilog->{Disk[{.5, .5}, Offset[{15,15}]]}]
(*VB[*)(FrontEndRef["025c6102-b371-4910-b09d-6d8567edb4d5"])(*,*)(*"1:eJxTTMoPSmNkYGAoZgESHvk5KRCeEJBwK8rPK3HNS3GtSE0uLUlMykkNVgEKGxiZJpsZGhjpJhmbG+qaWBoa6CYZWKbomqVYmJqZp6YkmaSYAgBv4hUM"*)(*]VB*)

Improved PlotLabel for Graphics3D

We have enhanced the PlotLabel option in Graphics3D functions to support more flexible labeling - not only text:

SphericalPlot3D[1, {\[Theta], 0, Pi}, {\[Phi], 0, 2Pi}, PlotLabel->HoldForm[(*SbB[*)Subscript[Y(*|*),(*|*)0,0](*]SbB*)]]
(*VB[*)(FrontEndRef["2be2fdb8-5dee-493a-b6a2-f362fb470b08"])(*,*)(*"1:eJxTTMoPSmNkYGAoZgESHvk5KRCeEJBwK8rPK3HNS3GtSE0uLUlMykkNVgEKGyWlGqWlJFnomqakpuqaWBon6iaZJRrpphmbGaUlmZgbJBlYAACW2RYv"*)(*]VB*)

Bonus: LLM Autocompletion

This is totally optional feature, which was hidden in our modules for a long time.

In general it works on all kind of languages, including English 🙂

By the default it uses the same endpoint as assistant chat window, i.e. OpenAPI API.

To enable LLM autocompletion find a checkbox in the Settings menu under the "AI Assistant" section.

And do not forget to set API Key in the designated field to authenticate your requests.
