looks like one uses dots and the other is more of a bargraph

That's it?

Wait, does not dot also list the individual val's that fall in the range?

anonymous · Answer

(ex) suppose the bin was 0-5, and we had 6 cases in there. In this part of the graph, we would have 6 dots going up from it right?

im not red up on the subtleties, but they simply look like different methods of representing the data in a rather simplistic graphical manner http://www.cs.uic.edu/~wilkinson/Publications/dots.pdf

anonymous · Answer

Ok let me cut down on the statistics terminology:

Suppose we have a section of the chart that represents the range 0 - 5 (ie. values from 0 to 5). If we had 6 values that fell into this range (ex. 3, 4, 2, 3, 3.5), would there be 6 dots coming off from this part of the graph, similar to how the histograph would have a bar coming out from this part?

yes, or even like a stem and leaf plot
