While trying to use the tooltip for each ring in a multiple ring donut chart using d3js , while hovering on the ring it just shows the values for the first child . Below is the code which shows the rings as well as the tooltip . What would I be doing in order to get all the correct item on hover.How do I iterate through the json to get the correct tooltip.
