I needed to have:
self.lines = self.newplot.plot(self.plot)

from the data I brought in I got the following when the variable
above(self.plot) was inserted:

self.lines = self.newplot.plot(u'plot')

So by applying eval:

self.lines = self.newplot.plot(eval(self.plot))

It then inserted the following  when the variable self.plot was used:

self.lines = self.newplot.plot(eval(plot)

no u'stringhere' in the second version with eval around the variable.


I hope that makes it clearer. Otherwise I might have to let you borrow
my Windex to clean the screen.
