If the scripts work fine outside LyX then your problem is with your

version 2.0.3 which is the one I have tested in my debian system.

The converters are defined in the configuration file LyX. If you 
could take a loom at it and post the lines where you file formats 
and the converters are defined, one could see if there is something

All of this seems ok, take into account that if you are on Windows the 
correct converter line should be

\converter "pygr" "png" "python -tt $$i $$o" ""

but it would be better if you to have
\converter "pygr" "eps" "python $$i $$o" "" on Linux
\converter "pygr" "eps" "python -tt $$i $$o" "" on Windows


Thank you for your inputs.

The problem is that I'm using LyTeX 2.0.1 and it comes bundled with its 
own Python.   The Python that is in the

directory did not contain the python modules this needs.

I copied my version on my C: drive to the USB drive where LyTeX is and 
now everything is working well.


Thanks.

Python is the best scripting (and general purpose programming) language
ever invented. Not only for scientists. 

If you're using a computer intensively to earn your living, you *should*
learn it. Otherwise you're missing *something*, in terms of
productivity you can achieve.

There are numerous possibilities using converters like this - ranging
From simple scripts (one can also call R like this if one does not need
a single session and only wants to do simple graphs), to calling complex
simulations... whatever produces graphs. Actually not only graphs, also
text, e.g. tables generated should work with the correct export format?

Alex - I think it would be a good idea to add this to the LyX wiki.

Re: Python Graphics in LyX [was: Python bindings]

[Wolfgang Engelmann]

I retryed again and now got the PythonGraphics>LyX converter after 
reconfiguring, but running it gives me:


LaTeX Warning: File `0_home_we_Lyx_PhytonGraphics_example.pdf' not found 
on inp


ut line 80.
shouldn't it load example.pygr, which I selected in my folder 
PhytonGraphics containing all the files supplied by Alex?

Do I have to use instead of view>pdflatex something else for export?
Wolfgang



! Package pdftex.def Error: File 
`0_home_we_Lyx_PhytonGraphics_example.pdf' not


found.


See the pdftex.def package documentation for explanation.

Type H  for immediate help.

If you have followed the little manual you know in tools - 
preferences there is two options, one that says file types and the 
other says converters

in the first you define the Python graphics file type
in the second you define the converter

regards
Alex



Thanks Alex, still not there.



First: Could one change in the instruction of the PythonGraphics.lyx
Define a new file format, name it Python graphics, extension pygr and 
vector image format ticked
to: Define a new file format in tools>preferences, name it Python 
graphics, extension pygr and vector image format ticked


Second: in Converters - Converter Definitions I guess I have to add 
python $$i $$o in the Converter: line. However, Add on the right side 
of the Converter Definitions is greyed out. So, how do I do that?

Dear Lyxers!

Studying a little of python and LyX I have reached to this feature that makes 
LyX show and process python graphics. Thanks to Rainer M Krug for the hints. I 
share this contribution for LyX under LGPL license, so everyone benefits from 
it. Good luck and happy lyxing!

  Trying
   # python example.pygr x.eps
  I saw, I had to install matplotlib and pandas. Thats OK, this example shows 
now in lyx too.
  Fortunately it was included in debian package manager.
Indeed, to obtain python graphics matplotlib is required, pandas is a robust 
library to handle with complex data. Both are in any package manager. The fact 
that this displays in lyx too is a very nice extra. My first intention was to 
have a module that insert python code and executes it, but this way is far 
simpler and reaches the same objective.
  But the try
   # python example2.pygr x.eps
  leads to
   ImportError: No module named seaborn
  After installing also python-pip and using
   # sudo pip install seaborn
  I got the expected output.
  This should be documented somewhere I think.
  Nice work.
   Kornel
In this case my intention was to show that any other python library can be used 
as well, and it is expected a little knowledge of python from the user, since 
it is the user itself who will build its own graphic script. But your hint is 
valid, it should be documented how to obtain extra python packages too.

Alex

Re: Python Graphics in LyX [was: Python bindings]

[Murat Yildizoglu]

Thanks Alex,
That opens new and nice perspectives.

I have just thought about another possibility: Since the Sage software 
uses Python as a glue, it must be also possible to use the Sage module 
for LyX to make computations in Python in Sage and include the results 
in the final PDF file.
That reminds me that I should check the Sage module for the last version 
of Lyx (have not had any time to look at it yet).


Best regards,

Murat
