Regarding the Zoomable Sunburst and Zoomable Icicle charts…
When you drill down into these charts, the parent category label can disappear, leaving you looking only at the children labels. Is there any way, upon clicking, to put the parent label in a variable and display it somewhere on the chart (the donut hole in the Sunburst, or the left-hand column on the Icicle)?
A related question: I’m using HTML divs to display the chart on one side of a web page, and explanatory text beside it. Can I get any level-information from the current status of my drill-down into the chart, and display it in my other div?
