Nope, it's not that. You can just change your map(int, foo) calls to
use float. (But that said, you don't need map, as you're operating on
one item at a time.)
Hmm....
try changing the following.
for x in data:
y = str(x).rstrip('\t\n') #This will remove any stray tabs or
newlines on the end.
( temp11, temp22, pyra11, pyra22, voltage11, current11) = y.split('\t')
(Also, you could probably rewrite like this)
temp1, temp2, pyra1, pyra2, voltage, current = [],[],[],[],[],[]
data_file = open(os.path.normpath(self.TextFile.GetValue()), 'r')
for x in data:
y = str(x).rstrip('\t\n')
( temp11, temp22, pyra11, pyra22, voltage11, current11) = y.split('\t')
temp1.append(float(temp11))
temp2.append(float(temp22))
pyra1.append(float(pyra11))
pyra2.append(float(pyra22))
voltage.append(float(voltage11))
current.append(float(current11))

'There is only one basic human right, and that is to do as you damn well please.
And with it comes the only basic human duty, to take the consequences.
