Help creating custom charts

Hello!! I’m using queries to get the data I want for a graph. The graph only uses two values but each comes from a document with more data behind it (our internal source documents). This data wouldn’t be displayed in the charts but each count on the chart references one behind the scenes. Is there a way to include it in the overall view so someone viewing the chart data can see it? My current work around is to make a second chart thats a ‘table’, but would be great to have the two in one.
