[Matplotlib-users] alpha settings in mplot3d
I haven't had a chance to look properly at the new mplot3d improvements that Ben Root has been working on, but I wonder whether it is easy now to set the axis properties so that the patches that form the axes no longer have an alpha value of 0.5? I really want them to be solid. The use case is that I often save images in a vector format for editing within inkscape, do some fiddling, then re-export as eps or pdf. If there are any semi-transparent objects, inkscape will rasterize the whole image, so it becomes necessary to first go through and manually set the alphas of all these patches to 1.0 before saving. A cursory look at the new code makes me hopeful that this is now possible since the setting from _AXINFO has been moved to the Axis constructor. Does that mean I'll be able to do something like ax._axinfo['x']['color']=(0.3,0.3,0.3,1) with the new version?

To make it clear, the _axinfo dictionary is in the Axis3D object (of which there are 3 in a Axes3D object). So, it would be something like: ax.xaxis._axinfo['color'] = (0.3, 0.3, 0.3, 1) At least, in theory. Part of the reason why I did not want to make this dictionary official is because the above would not actually work as expected. Although something similar for tick line colors might, for example. Because of the inconsistencies and because I did not want to paint myself into a corner, I have made this dictionary explicitly users beware. However, there is hope for your problem! Use ax.xaxis.set_pane_color((0.3, 0.3, 0.3, 1)) instead! Let me know if you encounter any other problems.

Re: [Matplotlib-users] alpha settings in mplot3d
Thanks Ben, that works nicely. Good work :) (except that inkscape is not nearly as good as matplotlib itself at optimising the resulting vector-based pdf to keep the file size down - not mpl's fault though). I just remembered, while trying this out, that there are two of every object forming the axis parts - two of every patch, grid line, tick line and label. It was this way before the latest changes also, but is there a reason, or is it a bug? It doesn't impact visually though. thanks for the great work on this, Gary On Wed, Jul 20, 2011 at 12:41 PM, Benjamin Root ben.r...@ou.edu wrote: On Tue, Jul 19, 2011 at 9:25 PM, gary ruben gru...@bigpond.net.au wrote: I haven't had a chance to look properly at the new mplot3d improvements that Ben Root has been working on, but I wonder whether it is easy now to set the axis properties so that the patches that form the axes no longer have an alpha value of 0.5?

I haven't noticed the doubling issue, but I have my suspicions. It is likely an inadvertent side-effect of the current design. I will look out for that, but I am hopeful that this will resolve itself as I continue to refactor mplot3d. If the problem hasn't resolved itself before the next+1 release (i.e., whatever will come after v1.1.0), then ping me again for a reminder.
