#184 pyFoamSamplePlot: underscores in set name

[Mithrandirrr]

When a set name in sampleDict contains an underscore, pyFoamSamplePlot exits.

Error in /usr/bin/pyFoamSamplePlot.py : PyFoam FATAL ERROR on line 263 of file /usr/lib/python2.6/site-packages/PyFoam/RunDictionary/SampleDirectory.py: The data in file center_line_P.xy is neither vector nor scalar: ['-8.3744e-05', '27.323']

Removing the '_' from center_line solves the problem.

The command I ran is:

pyFoamSamplePlot.py . --field=P --directory-name=sets --picture-destination=samplePlots

[Bernhard Gschaider]

The problem is that the filename is used to determine the name of the line and the fields (which are spearated by '_'). So to find out how many data sets are in the file PyFoam would have to look into the files too.

The problem is further complicated by the fact that
- lines can of course have more than one _ in their name
- field names may also have _ in them
- vectors can be distinguished from scalars only by the number of columns

So a file a_b_c_d with 4 columns can either be
- a line 'a' with three scalars b, c & d
- a line a_b_c with a vector value d

I'll have a look whether there is a STABLE way to fix this
