No, I didn’t want to drag 50 states into the right order, especially when some of the values are relatively close and I couldn’t see them well. (Or maybe you weren’t seriously asking that?)
I actually disagree that most of the time there would be multiple values for a single category – maybe that’s the case in the data you’ve been working with, but it’s not the case in most of the data I’ve been working with. Consider, for example, any data set that has one row/case per person – and several numbers associated with each person (height, weight, shoe size, etc.) and I’d like to see the distribution of heights as a case value plot, ordered, in the way they would be if people were standing in a line.
Perhaps the whole realm of case-value plots is not one that CODAP wants to support – but I would argue, at least for the age group I’m working with, they are a very useful representational form for students to work with, certainly before they learn to write formulas. (I’m not quite sure how the formula works, by the way – can you explain? But it’s certainly not an entry-level formula..)
