Thanks, Bill! I’m surprised no one reported that previously – but maybe people haven’t been using datasets with lots of missing values. At any rate, glad to hear that it’s been fixed and we’ll look forward to seeing the new version in January.
Thanks, Bill. We think it has to do with missing values, too, but couldn’t do much more diagnosis than that. Do let us know when it’s been fixed, since it’s part of a module we’re teaching in February.
And thanks for the Google drive link warning…we generally use sharing, but I forgot..
Also, I think the timestamp on the forum is buggy – it’s telling me that you sent your reply at 5:49PM on 12/25. Unless you’re in Europe somewhere?
Happy holidays!!
Any ideas about when that “append” work might happen? We’re writing activities to be done in February…
I think I’ve figured some of it out – it has to do with my having two different Google drive accounts, I believe — so don’t spend too much time looking into it. There may be something wrong, but I think I can fix it by being more careful which account Google Drive is logged into.
I’ll try to attach something again – apparently the previous file was too large (it was an image file.) But the dataset is only a single level, so it’s not exactly the situation you describe. Here’s a link to the file.

I’m still a little confused about why this DOESN”T work…If I sort the TABLE, then the rows are in a different order – why don’t they end up on the graph that way?
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..)
Being able to get a histogram with a count axis would definitely help with this issue – is there a chance that will happen in CODAP? This is a request that came up in the context of analyzing some climate data with the Data Jam folks, which I can post about at some point.
I’d like to weigh in on this, since I actually disagree with the decision – and didn’t realize that Fathom did it this way, either. I think there should be consistency in how we think about the Y-axis and it should ALWAYS be that lower values are further down. If not, we get the attached counter-intuitive graph, in which a “perfect” correlation is represented as a line with slope -1, rather than 1. This seems wrong to me.

Bill –
Does this meant that the ordering is “fixed” after you drag the attributes into the other you want? So that the next time you used that variable, the categories would have the new order?
The dataset is on Google drive – did you try one that’s on Drive? I just did it again and the same thing happened You have to add just one case, using “Add Case.” I added it at the bottom.
