I just tried to updated 37 packages and the update system failed, first because biopython had a md5sum mismatch and then the whole update chain broke down and I had to manually click-close 30 windows telling me: The package manager has encountered error PackageManager is busy. Please wait until the current operation is finished. So, is there really hope that this works until next week?

Something like this: mayavi2 -d test.vtp -m Glyph -s"glyph.glyph_source.glyph_source=glyph.glyph.glyph_source.glyph_dict['sphere_source']" does not work. ("glyph" not defined) Any hint? TIA Cheers, </pre> Fred 2013-06-14T08:05:12 http://comments.gmane.org/gmane.comp.python.enthought.devel/32019 <pre>Hi ! is there a way to choose an icon to be displayed in the taskbar and/or in the title bar when my traits application is running ? For example, we can take this example : http://docs.enthought.com/mayavi/mayavi/auto/example_mayavi_traits_ui.html Y. _______________________________________________ Enthought-Dev mailing list Enthought-Dev-oRDGkvazHdacsI7C1d+pp9BPR1lH4CV8&lt; at &gt;public.gmane.org https://mail.enthought.com/mailman/listinfo/enthought-dev </pre> Yohann Morille 2013-06-13T20:28:18 http://comments.gmane.org/gmane.comp.python.enthought.devel/32018 <pre>Hi, Is there any way to freely rotate Chaco plots? In part of our application, we use a mixture of LinePlots and ScatterPlots to display data tied to physical locations in an XY plane. While exploring the plot, it would be useful to allow the user to freely rotate it (e.g. to align some portion of the data with the long dimension of their monitor). I've been digging around in the Chaco documentation, and I'm not finding anything relevant. It seems like we should be able to define a single transform that's applied before any drawing occurs, but I haven't had much luck. Am I on a wild goose chase, or is this doable with Chaco?

I have a 3D plot with ScalarCutPlane module. I want to retrieve the cut plane origin and normal every time when cut plane is changed. Is it possible to add some observer to the cut plane movements and process this event in some callback function?

I realize that you can input a fourth parameter, 's', that you can use to give color to your points. As it turns out though... the scalars provided in 's' do not only affect color, but the size of the point as well. Is there any way to work around this so that my scalars only affect the color and not the size of the points?

I had an idea to make simplest as possible 3D barchart animation, but Mayavi window just stays still. It's doing something, at least it's reading the data as instructed, but scene never changes: --------------------------------------------------------- import h5py import numpy as np from mayavi import mlab with h5py.File('sk.h5') as h: c = mlab.barchart(np.array(h['12'][0])) &lt; at &gt;mlab.show &lt; at &gt;mlab.animate(delay=100) def anim(): f = mlab.gcf() while 1: for ar in list(h): print('Updating...') c.mlab_source.scalar = np.array(ar) f.scene.render() yield anim() --------------------------------------------------------- Arrays stored in h5 file are with (15,30) shape. I googled about it, but all I found was similar reports without answer. Hopefully someone can point me in right direction. </pre> zetah 2013-05-31T04:52:22 http://comments.gmane.org/gmane.comp.python.enthought.devel/32007 <pre>Hey everyone, I cannot seem to find anything in the docs, but I have an issue where my GUI has a button which, when pressed, goes about generating a plot. This can take awhile, and the GUI usually freezes up. I've been trying to find a way to multithread it (with avoiding the issues of running any plot-displaying code in the thread, since GUI must run in main). My issue is how can I tell the GUI that the plot has finished and that it can display the resulting plot? I figured there might be a checker function of the form def check_for_plot(self, thread): if thread.isAlive(): self.after(500, self.check_for_plot(thread)) else: self.edit_traits() But there doesn't seem to be any built in function. I am wondering if anyone is aware of, or uses, a more efficient way to generate plots without holding up the GUI loop? Thanks again for all your guys' patience!

Mayavi2 4.1.0-1 (from Ubuntu 12.10, amd64) always crashed when I opened any vector VTK file, added "Vorticity" filter, then added "Extract vector components" filter and finally when I tried to add "Scalar cut plane" module. The same repeated with another file, too. I can send the files to reconstruct the scenario, if needed.

The problem that I am not sure how to overcome is: how can I use dynamically created mapped traits (I suspect that I can't really)? Is there some other way to simply make use of the mapping function associated with a mapped trait rather than creating an instance of the trait? I want to use the existing ColorTrait mapper because I need the code to be toolkit independent.

However, one thing is very noticeable, there's a considerable delay for the context menu ( in the tree editor ) to pop up. This takes ~1sec on a very recent macbook pro. I hope you might have a suggestion how I can narrow this down?

ScatterPlot triggers a complete redraw on the change of any metadata: def _either_metadata_changed(self): self._selection_cache_valid = False self.invalidate_draw() self.request_redraw() ScatterInspectorOverlay uses the 'hover' metadata key to determine which data point to highlight. The combination means that whenever we update 'hover', we don't just redraw the overlay (presumably a cheap operation), we redraw the entire scatter plot. It's not just ScatterPlot, though: ScatterInspectorOverlay requests a full-plot redraw on metadata changes: def metadata_changed(self, object, name, old, new): if self.component is not None: self.component.request_redraw() return I've attached a modified version of the scatter_inspector.py example from Chaco 4.2.0 that prints whenever ScatterPlot is rendered, and disables ScatterPlot's redraw-on-metadata-cha</pre> Brennan Sellner 2013-05-08T18:36:18 Search the mailing list at Gmane query http://search.gmane.org/?group=$group=gmane.comp.python.enthought.devel
