Dimple.js Axis Labels

I have a dataset where each row has an id and a name property. The id property is the unique key, the names may be duplicated. I want the name to be shown on the category axis of a Dimple.js chart.

If I use "name" as the argument to chart.addCategoryAxis, the correct labels are drawn, but users with duplicate names are grouped into single bars. If I use "id" as the argument, the bars are separated but with the wrong labels.

Is there a "Dimple" way to achieve this, or should I just either :

• Write a manually axis formatter to convert from id to name, like here : https://github.com/PMSI-AlignAlytics/dimple/issues/99
• Access the axis.shapes afterwards and change them?
