Austin,
To make sure your data is created correctly, Can you create a page that displays the Chart object and all Dataset and Datapoint objects? You'll need to have a Dataview and retrieve the Datasets and Datapoints via association (since the entitys are not persistable) using nested Listviews.
I am guessing that there is something going wrong in the microflow that creates the data - also, both Modelshares you included in your post pointed to the same microflow, so I couldn't see the Sub microflow.
Hope that helps,
Mike

Austin,
I made a small test in a sandbox project I have. You can download the MPK here: http://www.filehosting.org/file/details/724022/DomJoint.mpk Once you download it, open it using Modeler 7.10. The home page is a ChartJS bar chart that is like the one you described. You can take a look at the source microflow and maybe that will help you get yours working.
