Not that I know of. There is a 2D data point plotter called PlotMorph on SqueakMap at http://map1.squeakfoundation.org/packagesbyname
I saw a sample here: http://minnow.cc.gatech.edu/squeak/3231, but he didn't say how the graphs were made. Is there an easy way to do this in Balloon?
The 2D WavyLines display was done with a series of simple open PolygonMorphs which were scaled by the data series maximums and minimums to fit the display area. The 3D plot on the SWiki page you referenced was done by constructing a triangle mesh from the data points. I copied one of the examples in the Balloon3D-Tutorial-Demos (which is in the Squeak 3.8 "full" distribution) and modified it to display my mesh.
You might also want to look at the PTexture.cs.gz example code towards the bottom of the page at http://minnow.cc.gatech.edu/croquet/ProceduralTextures which is a fairly simple example of a contour plot.
I also saw KGraph, but it won't install.
As Josh says, this is for a different class of graphs, not what you want to do.
Function Plotters (http://mate.dm.uba.ar/~caniglia/Andres/ fplot23.zip) also looks good, but it dies after trying to send messages to nil when I try to load it.
This does look pretty cool. I suspect that it was written for a different version of Squeak than you are running. There could be some other mismatch that is causing the undefined object reference. Maybe you could forward the entire walkback listing? It should also be at the end of the SqueakDebug.log in the Squeak base directory.
Cheers, Dave

http://mate.dm.uba.ar/~caniglia/Andres/gallery.html This graphs could be done with MathMorphs . I do a port to 3.9 a few monts ago. Also I have a minimal image SqueakLightMW.2.zip , in case you need.

The old MathMorphs is actually where I found the Function Plotter (which I think may just be 2d, not sure about that). Where can I find the 3.9 port? I didn't see anything on SqueakMap, and the project in SqueakSource seemed empty (though I didn't actually try connecting to the repository).

Milan should put the last on SqueakSource, some missunderstanding.
Tomorrow I put all .morphs converted to 3.9 in : http://community.ofset.org/wiki/MathMorphs what Serge created
And http://community.ofset.org/wiki/MathMorphs_Revival_Project.
I suppose is 2d package, my interest is not math , is about loading/converting any code produced in any Squeak in my SqueakLight and also in 3.9. Most of original code works in 3.9 with some adaptation, I check and actualize info.

Here you got the last what lets XYPlotter example1 asMorph openInWorld working. Some is still buggy in Squeak 3.9b 7054, I fix as soon as could.
Also I put two "intelligent" morphs converted from old code what could load in 3.9 without load the rest of MorphicWrappers or another code
ModularIntegers.morph.gz LinearAlgebraI.morph.gz
Enjoy.

Does anyone know how to draw lines in Balloon3D? I want to add simple, straight lines to a surface graph (based on the surface graph tutorial).
Thanks,

It's not supported by the plugin. There are hooks for polylines in the API though, I once implemented those using Balloon2D (meaning they could not be hidden behind a 3D mesh). Very long time ago, not sure if I can find it - it was more a hack than anything else.
Your best bet would be to just construct a tube mesh connecting the nodes.

Well, that's disappointing. I was hoping to make lines that would appear at a given width regardless of the distance to the camera. These would be the X, Y and Z origins for a data surface, so they would need to be able to correctly penetrate solid objects.
The tube idea is probably the best bet--though they may disappear when I zoom out.

You could adjust their width on the fly depending on current zoom factor / distance, which would mimic a line primitive. You could also make them longer, something that a built-in line would not do automatically.
Doing this on your own is also more predictable - like, Direct3D would not even support wide lines, whereas OpenGL does.

Hi Edgar,
Thanks for putting it up. Earlier, (about a month ago) I have converted your MorphicWrapper changeset to .mcz. I started working on MathMorphs when I got stalled by work, vacation, life, and other roadblocks. I will try to finish that during next 2 weeks, or at least find it is not that easy. Hopefully having it in .mcz would make collaboration easier.
Later, Milan

Ok. Back to notes and private emailing. I just find my quick cs for having something public lost "aerial typing" in last 3.9.

This turns out to be a very cool package by the way. I used it once for some data analysis, and discovered to my surprise and delight that the points on my graph could be clicked to explore the objects behind them. With a little bit of tweaking, I soon had something that looked like an ordinary 2-D graph, but it reality was a fully interactive browser for a complicated set of data. Really nice.
