Labels on my chart are showing over tooltip, which doesn\'t look very nice. I tried to play with zIndex, but to no result. How can I make tooltips not transpare
zIndex
If you set tooltip.backgroundColor to "rgba(255,255,255,1)" you'll get tooltip with "no transparency"
You will have to remove useHTML: true in the pie settings.
Fork of your jsfiddle: http://jsfiddle.net/kairs/Z3UZ8/1/
tooltip: { backgroundColor: "rgba(255,255,255,1)" }
