matplotlib-users Mailing List for matplotlib (Page 2)

Using the latest SVN matplotlib, the TkAgg backed does not get built 
even though all the libraries are installed (Linux 64-bit). The 
following error message occurs during the build:

Tkinter: no
         * Using default library and include directories for
         * Tcl and Tk because a Tk window failed to open.
         * You may need to define DISPLAY for Tk to work so
         * that setup can determine where your libraries are
         * located. Tkinter present, but header files are not
         * found. You may need to install development
         * packages.

This is even though lib64tk-devel and lib64tcl-devel are installed. 
Strangely enough, when I remove lib64tcl-devel, the script proceeds 
and picks up Tk, but it still can't determine the location of the 
libraries (complains about not finding tkConfig.sh) - the build proceeds 
but later fails because tcl.h is not found.

With both the tcl and tk headers installed, the only way actually to 
build the TkAgg backend is to force it by
	[gui_support]
	tkagg = True
in setup.cfg. I still get the Tkinter error message given above, but 
the backend builds successfully and I seem to be able to use it 
without errors. 

[jr@blikbrein ~]$ locate tkConfig.sh
/usr/lib/tkConfig.sh
/usr/lib64/tkConfig.sh
/usr/lib64/tk8.6/tkConfig.sh
[jr@blikbrein ~]$ locate tclConfig.sh
/usr/lib/tclConfig.sh
/usr/lib64/tclConfig.sh
/usr/lib64/tcl8.6/tclConfig.sh

Sorry, had not yet noticed the option for more verbosity in matplotlibrc. The
problem seems to be that some component related to wxagg wants to create the
symbol "printer" which, because my printer was called "printer", apparently
already existed. Renaming the printer on my system solved the problem. The
same applies to PDF. If you install cupspdf the problem also appears and
after renaming it to e.g. CUPS_PDF disappears.

Hello,

I was wondering if it is possible to hide some data on figures using a say
right click option to any of the legend entry and make it temporarily
hidden/visible to better analyse the rest of the data?

Check this screenshot for example:

http://img25.imageshack.us/img25/9427/datahiding.png

The red data clutters the rest of the figure, and I would like to be able to
hide it temporarily so that I can investigate the other two relations more
easily.

Any ideas? or alternative solutions?

Thanks.

Yang,

You might want to consider reading this thread. It was recently discussed in
mpl list:

Hi, recently I've been using the beautiful (and easy-to-use) pycha[1] 
package for simple bar charts:

http://img522.imageshack.us/img522/7139/tput.png

So far, pycha is the closest thing I've found to Office 2007-caliber 
aesthetics.  However, pycha is much more limited than matplotlib, and I 
happen to need error bars on the bar charts to illustrate standard 
deviation.  Is it possible to do produce (for instance) the above chart 
using matplotlib (preferably without lots of coding)?

Here's the pycha homepage: http://bitbucket.org/lgs/pycha/wiki/Home

Thanks in advance!
