How do I create a CORRECT histogram?

[Brian Chisholm]

I'm trying to create a histogram for 50 values. I've put in the upper bounds
as my bin values, as was posted by another user. However, the frequency
output chart that is created by the histogram does not match the same
frequencies that my data shows. Many times, the frequency is off by one,
either positive or negative.

Moreover, I want the lower bounds of the data set to show up. How do I do
that?

Perhaps Mike Middleton's "Better Histograms" approach will help:
