CRONTAB - one python script is not running
Hi!

I'm using a RaspberryPi with standard Raspbian.
Currently I'm working on some sort of weather station.

For now I have three python scripts - one which is updating txt files for website - update1m.py ( it will not be necessary in few next days so I'll delete it) , second one for updating mysql datebase with measurement - updateDB.py and the last ( this one is generating problem ) for generating chart out of measurements gathered in database.

I'm a beginner so propably my methods are as dumb as it is possible but this is the reason why I'm asking you for help.

Via command line im running - sudo crontab -e.
My crontab looks like this:

Code:
@reboot python /home/pi/meteo/update1m.py

@reboot python /home/pi/meteo/database/updateDB.py

@reboot python /home/pi/meteo/imag.py

*/1 * * * * python /home/pi/meteo/update1m.py

*/1 * * * * python /home/pi/meteo/database/updateDB.py

*/1 * * * * python /home/pi/meteo/imag.py

First two scripts are running properly after reboot and every minute.
Unfortunatelly last one imag.py is not running with cron. It is working properly if I simply execute it with python ./imag.py but not with cron.
I'm sure that path for script is ok.

Do you have any idea why it is acting like that?

Regards,
Mateusz

PYCENTRAL()															       PYCENTRAL()

NAME

       pycentral - register and build utility for Python packages

SYNOPSIS

       pycentral [-h] [-v] <cmd> [<cmd options>] [<args>]

DESCRIPTION

       pycentral
	provides support for installing python modules independent
	of the current installed Python version and handling
	byte-compilation and -removal tasks in installation scripts.

OPTIONS

       -v, --version
	      Limit the output to the version numbers of the python versions.

       -h, --help
	      Print a help text.

       pycentral has the following sub commands. For fine grained help, call: pycentral <cmd>.

       bccompile
	      Byte compile .py files in a package.

       bcremove
	      Remove the byte compiled .py files.

       list   List all managed files.

       pkginstall
	      Make a package available for all supported runtimes.

       pkgprepare
	      Prepare a package for all supported runtimes.

       pkgremove
	      Remove a package installed for all supported runtimes.

       pkglist
	      List pycentral-managed files of a package for all supported runtimes.

	      move files to pycentral locaation, variable substitutions (called by dh_pycentral).

       pycentraldir <package>
	      Show the installation directory used by pycentral for <package>.

       showdefault
	      Show default python version number. Deprecated, use pyversions(1)

       showsupported
	      Show the supported python versions. Deprecated, use pyversions(1)

       showversions
	      Show version numbers of supported python versions.  Deprecated, use pyversions(1) dh_pycentral, should not be called directly).

       version
	      Show the pycentral version.

FILES

       /etc/python/debian_config   is	searched   for	 the   attribute   overwrite-local.    If   set   to   1,   or	True,  existing  files	in
       /usr/lib/pythonX.Y/*-packages are overwritten with symbolic links to the pycentral install area. The default is to abort  the  installation
       of  a  package,	when files already exist. This behaviour may be useful, when python libraries were manually installed into this directory.
       The attribute byte-compile can be set to a comma separated list of the values standard and optimze to indicate how files  should  be  byte-
       compiled.
