Hi Łukasz,
It looks like very interesting. Let see how to solve your problems.
How did you install taurus? and from where?
I did a test installing from git and it works for me :
git clone git://git.code.sf.net/p/tauruslib/taurus.git taurus
cd taurus
git checkout 4.0.1
python setup.py install
in ipython
In [1]: import taurus
In [2]: taurus
Out[2]: <module 'taurus' from
'/usr/local/lib/python2.7/dist-packages/taurus-4.0.1-py2.7.egg/taurus/__init__.pyc'>
In [3]: taurus.Release.version
Out[3]: '4.0.1'
vi /usr/local/lib/python2.7/dist-packages/taurus-4.0.1-py2.7.egg/taurus/
# Set your default scheme (if not defined, "tango" is assumed)
DEFAULT_SCHEME = "eval"

for domain in data.keys():
AttributeError: 'EvaluationAuthority' object has no attribute 'keys'
I reported the attribute error in a taurus ticket (but it seems to be
innocuous ) for your purposes.
I attached you the taurusplot snapshot as I see.
If previously you had installed taurus3, please be sure that it was
uninstalled, maybe you have a conflict with the taurus launchers.
Could you run this code and say me if it works for you?
fromtaurus.qt.qtgui.plotimportTaurusPlot
fromtaurus.qt.qtgui.applicationimportTaurusApplication
importsys
app = TaurusApplication()
w = TaurusPlot()
w.show()
sys.exit(app.exec_())
Best,
Carlos
