I looked into this some more this morning, and discovered that this tick behavior also occurs when yaxis.tick_right() is called. xaxis.tick_top() behaves as it should, and the only difference I noticed stepping through a script with the debugger is that at the end of set_ticks position, YAxis does the following, but XAxis does not: for t in ticks: t.update_position(t._loc) I don't know what is this blocks purpose, adding it to YAxis didnt seem to have any effect.

[matplotlib-devel] figsize anomaly in pdf
Hi,
using the attached script to generate one pdf and one png of the same
figure. I get a 800x600 pixel png which is expected for a 8x6in figure
at 100 dpi. But for the pdf I get 11.11x8.33in as determined from the
document properties dialog in acrobat reader. Looking at the file
information on a mac it reports the size as 800x600 for the pdf.
Doing some more digging it turns out acrobat reader reports a correct
size for the figure if I set dpi=72 when calling savefig. Perhaps there
is some dpi information that needs to be saved with the pdf file?

x=arange(0,2*pi,0.1)
pylab.close("all")

pylab.plot(x,sin(x))
pylab.savefig("figsize-1.png")
pylab.savefig("figsize-1.pdf")

[matplotlib-devel] Tk-window doesn't show full figure
Hi,
One annoyance with the TkAgg plotwindow is that it doesn't show the full
plotarea. Comparing the plot result saved to png in visible-area-tk.png
to the screen shot of the tkagg window in visible-area-tk-window.png you
can see that there is a grey border covering some of the area at the edges.

[matplotlib-devel] 3d support
Hi I want to write an application which includes multidimensional visualization. I tried running simple3d.py but it is sloww! Also, I'm not sure if the Navigation Toolbar is working properly. I looked into VTK and it certainly has good performance and good navigation but another steep learning and probably overkill for interacting with simple 3d plots. Anyone have any thoughts on this?

We are working on making Mayavi2 (https://svn.enthought.com/enthought/wiki/MayaVi) suitable for what you want to do. You can have a look at http://gael-varoquaux.info/blog/?p=3 for a demo of the capabilities and the interface. This is only part of Mayavi2, as Mayavi2 also provides a fully-fledged visualisation application. Mayavi2 is based upon VTK but strives to make it interactive and to provide a simple API. It is still in flux and documentation is sparse (I am planning to address this problem this week end). Moreover some people find installation painful. We are working on that and in the mean time we are very willing to help people if they have difficulties with the instructions on the webpage. If you want more info or help of any kind, the relevant mailing list is https://mail.enthought.com/mailman/listinfo/enthought-dev .

I was just experimenting with Mayavi2 when your mail arrived! Thanks.
