I found multiple plots in matplotlib. You need to specify which one 
you're using.

The first thing you need to do is create a small self contained example 
of your problem.

State the problem: Plot does not create the output you expect.

Give an example:

plot( [1,11], [5,5] )

Explain what you expect the output to be:

You expect a line to be plotted from (1,5) to (11,5)

Explain what you actually see: ???

Note that it may be possible to correlate the data values and the output 
of the simple case in a way that shows you that you have in some way 
fundamentally misunderstood how the arguments should be passed to the 
plot function. If this is the case, work out what you need to do to fix 
the simple case, and then apply the same solution to your more complex 
data set.

If, for example, you see a line from (1,11) to (5,5) instead of a line 
from (1,5) to (11,5), then it might be that you need to combine the two 
lists into a single list of co-ordinate tuples, using eg:

plot(zip(list(results.keys()), list(results.values())))
