[Matplotlib-users] Widgets

[Stephen W. <ste...@cs...>]

As a new user of matplotlib, I'm surprised I haven't seen this
mentioned, offhand, in the mailing list archive.  I am not seeing the
redraw or close widgets on the plot windows I produce.  The platform is
Fedora Core 1, although I built on RHEL3 because matplotlib-0.60-2 won't
build on FC1 (some problem with tk-devel, apparently).

Your post says you are a new user but the content suggests you've used
matplotlib before.  In early versions there was both a redraw button
and a close button.  The former was there because sometimes the figure
would get into an inconsistent state (after exposes, or resizes for
example) but these problems were fixed and I no longer saw a need for
it.  The close button was dropped after Steve Chaplin pointed me to
some user interface design guidelines that argued close buttons should
never be placed on toolbars.  So it is by design that these are
missing.  Is this a problem for you?

As for the FC1 problem, perhaps Fernando Perez can comment - I
believe he has used matplotlib with FC1.  I have no experience here.

I have played with version 0.50 a bit before, but I asked about the
"missing" widgets because they're still in the online tutorial.  Plus, I
had thought the redraw button would be a convenient way to reset a plot
to its default after zooming and/or scrolling in one or the other axis. 
This last function is one I actually need, but I was unable to see
anywhere in the documentation how it might be done.

This turned out to be SOE (Stupid Operator Error).  I didn't have the
tk-devel and tcl-devel packages installed.  Unfortunately the lack of
tk.h and/or tcl.h causes so many error messages in the compile that the
line complaining about their lack is easy to miss.  Not a matplotlib
problem, I hasten to add.

Thanks for the responses.

Thanks for letting me know about the tutorial problem.  As for
resetting the axes to the original view, redraw would not have done
that.  In the next generation toolbar, I might be able to add a button
to support that.  It already has a forward / back button to navigate
between previous views.  By clicking back enough times, you'll get
back to your original view.  Still, if you are deep enough in, a
"reset" button might be nice.

Yep, you have to train yourself to find that first error, the rest are
often meaningless.

Er, it does?  I don't see them, at least not with either the default
backend on FC1, which I'm guessing is GTK, nor with the TkAgg one.

Incidentally, the on line .matplotlibrc example file still has the
"toolbar" keyword, which is gone, and is missing the "datapath" one.

Sorry for the confusion - when I sat "it already has...", I'm
referring to the next generation toolbar that is under development in
CVS.  Only GTK and GTKAgg have a prototype version of the new toolbar
in CVS.  

For the record, the default backend in the src distributions (*.tar.gz
and *.zip) is GTKAgg.  For win32, the default backend in TkAgg.

Which rc file are you referring to?  There is no reference to the
toolbar option in the 0.60.2 release, though it is in CVS and on the
web (should fix that one, though it is listed as experimental).  The
datapath was intentionally omitted - it exists for those who want use
it to set the data path but for most users the default is OK.  I just
changed this in my dev tree to include a commented out reference to it
to alert users that it is there.

Thanks,
