3D scatter / meshed surface color map

[mauri...@gmail.com]

Hello Julia users,

I would like to know if anyone knows how we can have 3D scatter plots or meshed surfaces color plots using Julia. 

My problem is based on four variables, so I'm trying to visualize the data according to these options.

Any idea or example code will be really helpful.

Thanks!

Is https://github.com/stevengj/PyPlot.jl#3d-plotting not what your need?

[Simon Danisch]

There is: 

http://www.glvisualize.com/examples/surfaces/

Which also supports any 2D/3D billboard (2D particles that keep facing the camera): http://www.glvisualize.com/examples/sprites/

If you need axes and labels right away, there is: https://github.com/stevengj/PyPlot.jl which supports 3D plots.

They're not really interactive though, from all I know.

I'm a fan of PlotlyJS.

julia> include(Pkg.dir("PlotlyJS","examples","3d.jl"))
scatter_3d (generic function with 1 method)

julia> scatter_3d()

It's interactive.

Pkg.add("GR")

using GR

z = peaks()

surface(z)

These are all really cool packages. Don't pick just one! ;)

One of these days I'll get GLVisualize working...

But unfortunately on Windows

INFO: Downloading pre-compiled GR 0.17.3 binary
=================================[ ERROR: GR ]==================================

LoadError: chmod: no such file or directory (ENOENT)

I could re-produce the problem on a fresh Windows installation.

Removing the downloaded archive leads to a chmod error, although I don't use this function in build.jl.

Will have to use another method to delete the file.

Nevertheless, the package should be installed ....

Oops, don't know what happened to the message asking me what version was it, and my reply to it (both disappeared), but here it goes again.
It eas trying to install v0.0.17

julia> Pkg.add("GR")

Hmm, is 'peaks' part of GR? Because

julia> using GR

julia> z = peaks();
ERROR: UndefVarError: peaks not defined

[Josef Heinen]

The build problem is fixed (in the master branch).

peaks() is part of GR - also in the master branch.

The next GR.jl release will be released this weekend.

[J Luis]

Ok, thanks.

In case you work with an IJulia notebook or Escher, you can use ThreeJS.jl. If you use Escher, you can also create UI's to control the variables and get the plots to update interactively. Please see the examples for more details. There isn't support for labels or axes currently though.
