How do you graph histograms on ti-89

If you are creating a histogram using a computer (or calculator) you will have labels for each (equally spaced) bar (eg, 0- <10, 10 - <20, etc. ) this way you clarify where exactly the values go.
If you are drawing a histogram wit put the data edge point in the bar that makes the groups even.
For example, if your lines were at 0,10, 20, 30, etc. then the first group is 0-9.99999, the next group would be 10 - 19.999999.
I hope this helps.

hey! in a histogram, if you have a data point that is equivalent to the "edge points," do they contribute to the left bucket or the right bucket of the histogram?
