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

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?

from taurus.qt.qtgui.plot import TaurusPlot

from taurus.qt.qtgui.application import TaurusApplication

import sys

app = TaurusApplication()

w = TaurusPlot()

w.show()

sys.exit(app.exec_())

Best,
Carlos

Hi Carlos,

Thank you for fast reply.
I changed in the tauruscustomsetting file the default scheme from “tango” to “eval”:
[cid:image001.png@01D1E813.B7AB1400]
when I try to run taurusplot I get error:
[cid:image002.png@01D1E813.B7AB1400]

I was on EuroPython and there was company that want to monitor devices in factory using python, I believe that taurus and Sardana in the future might be good solution for them.
I spoke with project leader and he was interested.
I would like to run some demo to present taurus magic :-)

Subject: Re: [tauruslib-devel] Taurus & data visualization from file

Hi Łukasz,
The problem is that taurus assumes as default scheme Tango (for backward compatibilities reasons), and for  that  you see this error. The modelchooser is trying to connect to a Tango DB, to avoid it you have two options:

a) Modify in the tauruscustomsetting file the default scheme. e.g.  use Eval
b) Give a non tango model name when you call the taurus widget. e.g. eval:1

What are you trying? What scheme are you planning to use?

I hope this help you!

Best,
Carlos

Hi Lukasz,
Which version of taurus did you have installed?
Only Taurus 4 is agnostic (It is not necessary to install PyTango if you will not use tango scheme)

You can install it from repository (sourceforge ) or pypi (https://pypi.python.org/pypi/taurus/4.0.1)

git clone git://git.code.sf.net/p/tauruslib/taurus.git taurus
python taurus/setup.py install

Your 2nd snapshot is a bug that is fixed in Taurus 4, but however could be some widgets that are still being Tango-Centric.

Best,
Carlos

Hello Zibi,

Thank you for fast answer!

I hoped to use taurus without Tango, I installed on VM only taurus (apt install python-taurus)
But I get an error:
[cid:image004.png@01D1E813.B7AB1400]

and:
[cid:image005.png@01D1E813.B7AB1400]

is it possible to use taurus without PyTango?

Thank you for your help in advance.

Hi Lukasz,

TaurusPlot is able to import data from a file:
http://www.taurus-scada.org/en/stable/users/ui/plot.html#choosing-what-is-plotted
I think that precisely CSV is not supported and the separator must be a white character and not a comma (you could try with the attached file).

One of the Taurus4 objectives was to make the development of the custom Taurus schemes more user friendly. Personally I have not written any yet, but this should be relatively easy. That means that you could write one for your file format and use Taurus widgets to visualize data from the file.

Have a nice weekend!
Zibi
