Something like this perhaps:
left, width = zip(*[(a, b-a) for (a,b) in values.keys()])
bar(left, values.values(), width)
That is, turn the sequence of intervals into a sequence of coordinates
where the bars should start (left) and another sequence of bar widths.
Then use bar to plot the values.

The hist function not only plots the histogram bars but computes them
from the data. Use bar when you already have the coordinates you want to
plot.
