I have a question about how the info popup advanced contentFunction feature works for the facet chart.
Based off the example in the docs, which is geared towards the time chart, it seems you can override everything from the title, to the body section.
As shown by this fiddle, it seems the contentsFunction for the facet chart only changes the inside contents. You also have no access to the name, or extra object on the objects passed into the preloaded data section.
Based off the fiddle example, I would ideally like access to:
data.preloaded.subvalues[0].name and data.preloaded.subvalues[0].extra when hovering over the first bar in the graph.
If it is not possible to override the title section, is it at least possible to get access to data.preloaded.subvalues[0].extra somehow in the contentsFunction?
