Ok.
I guess I got the trick (I hope ;-)

BTW, the following does not reverse the y axis:

        if ('cmap_image_plot' in plot.plots):
            p = plot.plots['cmap_image_plot'][0]
        else:
            p = plot.plots['colormapped_scatterplot'][0]
        if (self.reversed_y_axis_flag):
            p.origin = plot.default_origin = 'top left'
            plot.x_axis.orientation = 'top'
        else:
            p.origin = plot.default_origin = 'bottom left'
            plot.x_axis.orientation = 'bottom'

[chaco2] last version broken ?

Hi all,

I have updated chaco2 to the latest version (#16103).

Running examples/basic/contour_cmap_plot.py now fails:

Don't worry: if you have a screenie or two, that will be enough.  It's
a short time slot, so as long as we can demo something  we'll be OK.
You guys have provided plenty of good suggestions, and we also have
the fluidlab app that Pete Schmitt wrote.  So the screenies will be
good to show them what can be done with the type of data they're
familiar with at the end.

the real ETS source code: which one?

= The question itself =

Is ETS is continuing support for setuptools? It appears that Gaël 
Varoquaux packaging a version of ETS (or parts thereof) with setuptools 
stripped, but is this going to be the mainline future of ETS? Or are 
these special sources built just for Debian systems? Or am I missing the 
picture entirely?

The rest of this email is various stuff that you don't really have to 
read...

= Speculation from all the below, and a suggestion =

I surmise that Gaël is making a 2nd set of source releases for ETS. This 
version does not have a setuptools requirement, and the idea is that 
this will help Ondřej Čertík can package ETS for Debian. This ultimate 
goal, getting ETS in Debian, I strongly support, and this email is in 
the spirit of furthering this effort. I guess the reason that removing 
setuptools is thought necessary is because of the extremely hostile 
reaction to setuptools in some quarters of the Debian developer 
community. However, I note that setuptools and Debian can be made to get 
along. For example, see the Debian pacakges of python-opengl, trac, and 
python-turbogears, to name a few. I suggest that there is no need for 
splitting the ETS source distributions into a setuptools version and a 
setuptools-free version. Instead, I think that Debian packages of ETS 
can use the same source, and I'm happy to attempt to help, albeit only 
with the limited time I have available for this sort of thing.

mayavi2

Hi,

I can't get Mayavi2 to run on a winxp machine.
I installed with the enstaller, double clicked on the  
c:\python25\scripts\mayavi2-script.py.  it starts and draws most of  
the panels in the app but seems to die when creating the renderwindow.  
  it completely crashes python and the typical WindowsXP send bug  
report window pops up.

I've also tried running it from the command line and this did the same thing:

C:\Python25\Lib\site-packages\enthought.mayavi-2.0.2a1-py2.5.egg\enthought\mayav
i\scripts>c:\Python25\Scripts\ipython.exe mayavi2.py

mayavi2


So I'm pretty certain that my problem is coming from the creation of  
the scene.  The below works fine and the mayavi window opens and is  
responsive, until I select File->New->VTK Scene from the menu.  Then  
it crashes.

In [1]: from enthought.mayavi.app import Mayavi
Set Envisage to use the workbench UI: True
Set Envisage to use the workbench UI: True

In [2]: class MyClass(Mayavi):
    ...:     def run(self):
    ...:         script=self.script

    ...:

In [3]: mc=MyClass()

In [4]: mc.main()

This is not the problem, it's the VTK wrappers that were not updated.

What is strange is that I got it working on several computers with XP...

Re: mayavi2

I just installed Enthought packages, and it worked like a charm :|

Sorry, I cannot help you, I don't use XP at all. Hopefully by Monday
others that use XP will be able to pitch in.

Re: mayavi2

It could be a problem with your 3D driver. Do other 3D programs work correctly ?
