[matplotlib-devel] behavior of drawing in interactive mode

2011-05-22 Thread Mike Kaufman 
Hi,

After switching over from the MacOSX backend to the GTKAgg backend, I 
started notice a big change in drawing behavior.

Now I know that MacOSX is interactive all the time by [mis]design, so I 
wasn't surprised that I would have to add draw() commands when 
isinteractive()==False; however, when using the non-pyplot commands, 
i.e. ax.plot() rather than plot(), I must use draw() to render the new 
Line2D even when isinteractive()==True. This doesn't seem correct 
behavior to me. A lot of drawing just can't be done by the pyplot 
functions. You have to go to the axes functions.

On another, but related topic, I use ipython -pylab, and generally 
develop by using the `run -i file.py` syntax. I have found what I think 
is a bug where if I have a file that consists of:

cat >> file.py

I have started to try and merge my branch into the v1.0.x branch when I
discovered some interesting oddities, and I am not 100% sure how I should go
about resolving them.  My very first commit in the docfix/smalltypos branch
edited the doc/users/installing.rst document.  However, it appears that on
April 1, this file was removed from the repository and its information was
consolidated over to the INSTALL file.  However, even though I created my
branch from the v1.0.x branch on April 30th, none of these changes are in my
branch.  Therefore, given how many other changes that were made to the
documents, I wonder what other commits are missing.

Should I rebase my docfix/smalltypos branch with v1.0.x first or should I
use the conflict merge process to let the installing.rst file be removed and
make the changes I made over in INSTALL?  Or maybe another idea that I
haven't thought of?

No, it's public now so you shouldn't touch it anymore.

That button is very pointless - best to ignore it.

I went ahead with the merge conflict procedure, and everything appear to be
ok.  I had also noticed a few additional mistakes in the INSTALL file
currently in v1.0.x that I fixed as well.  I will double-check the
commit/merge before pushing it up.

I also noticed that the INSTALL doc on v1.0.x provided an equivalent command
of `apt-get build-dep` for Fedora/RedHat users.  I believe this information
should also be included in the install_faq.rst document (because it only has
the debian version).  I will make that a separate commit.

This is inherent in the design.  Pyplot functions are wrappers that do 
two things: call Axes methods on the current axes, and then call 
draw_if_interactive().  The rationale is that even when working 
interactively, one doesn't necessarily want to draw immediately every 
time a new Artist is created.  So yes, working interactively with the OO 
interface requires frequent plt.draw() invocations, making it only 
semi-interactive.

I think it is inherent in the -pylab mode of ipython, which is designed 
to run a script as if it were being run directly from the command line. 
To do that, it turns interactive mode off before running the script, and 
restores interactive mode to its original value afterwards.  A script 
intended to produce a screen plot includes a show() command.  Running 
such a script with ipython -pylab then leaves one or more plots with 
which one can interact directly or via the ipython command line--but in 
the latter case, if pyplot functions are not used, then draw() must be 
used for a redraw.

If you want the contents of the file to be executed exactly as if you 
had typed them in at the ipython command line, you can use the built-in 
execfile() function instead of the ipython %run magic.

The ipython %edit magic can also be used for this.

Ben, a quick look at installing_faq.rst shows some anachronisms: 
references to installing obsolete versions.  This is another worm 
barrel.  Those anachronisms are not the only problems with the file--or 
with installation in general.

I'll double-check for that.  Note that I am merely moving my changes over to
INSTALL, so whatever INSTALL has should be the final version.  Below is the
current diff between them.

On a separate note, I think there might be some unspecified requirements for
building the documentation.  On my newly set up Ubuntu machine, the build
gets to the thumbnails stage and recognizes that I have no thumbnails, and
then the process goes to sleep.  Maybe we have an error check missing
somewhere?

Right.  It looks like INSTALL is a slightly fixed-up version of the 
now-deleted install.rst.  I was referring to install_faq.rst.  Maybe 
that (or large parts of it) should go away, and be replaced by a 
reference to INSTALL?
