Sorry, uploaded the wrong .png, here is the correct one:

I really like the package you have created. Not being able to store text data is a showstopper unfortunately for pie charts, histograms, etc. Could this be fixed, please? The error in Python 3 is:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/numpy/lib/npyio.py", line 1215, in savetxt
    fh.write(asbytes(format % tuple(row) + newline))
TypeError: must be real number, not numpy.str_

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "xxxxx.py", line xx, in <module>
    yyyyy()
  File "zzzzz.py", line zz, in yyyyy
    PyGnuplot.s([x, y])
  File "/usr/local/lib/python3.6/dist-packages/PyGnuplot.py", line 74, in s
    _savetxt(filename, _array(data), delimiter=', ')
  File "/usr/lib/python3/dist-packages/numpy/lib/npyio.py", line 1219, in savetxt
    % (str(X.dtype), format))
TypeError: Mismatch between array dtype ('<U22') and format specifier ('%.18e, %.18e')

All thats needed is a way to save not just data but also text into the same file then.
Working on it.

The problems mentioned should me solved now;
Delimiter was changed form , to space.
Data should be saved in a more sane way. (hopefully)
Data storage should allow for text entries now.
(Which in its course removed its dependence on numpy).

Hope this works, please test it.

Thanks for the fix Ben. I can now put text labels in the data file and make a graph like this:

Thanks!
