TypeError: 'float' object is not iterable

When entering series data including a float (i.e 100.50) I get this error.

File "/usr/local/lib/python2.7/dist-packages/flot/init.py", line 218, in init
self._set_data()
File "/usr/local/lib/python2.7/dist-packages/flot/init.py", line 175, in _set_data
_x.contribute_to_class(self, 'X', self.data)
File "/usr/local/lib/python2.7/dist-packages/flot/init.py", line 82, in contribute_to_class
self._set_points(attr_name, data)
File "/usr/local/lib/python2.7/dist-packages/flot/init.py", line 118, in _set_points
s['_x'], s['_y'] = sample

@sardonic2 Can you post a code snippet showing how this Error happens? Tried to recreate with no success so far.
