We are working with multiple datasets with students and teachers and trying to map attributes. This is not working in either context. Here are two examples of datasets we are working with:
At the moment CODAP will only plot points from one dataset, and you don’t have the ability to choose which one. So, the only workaround I can suggest is that you make documents with just one of the datasets at a time.
We are working right now on giving you full control over as many point or polygon map layers as you like from as many different datasets as you like. This should release around the end of August.
