Daniel, Thanks for the reply and jsfiddle example. While I was in the process of removing superfluous elements to get the page to a minimum to demonstrate the issue I noticed it suddenly started working with the tooltips appearing on top as expected. My page is programmatically generated and there are no CR/LF characters or other formatting to make it more humanly readable and that was the issue. Simply adding a space at the end of the file, after </HTML> cause the tooltips to work as expected.
Here is the example where the tooltips appear 'under' the Treemap http://www.pluhk.com/Treemap-Tooltip-Under.html Here is the example where the tooltips appear 'over' the Treemap http://www.pluhk.com/Treemap-Tooltip-Over.html The only difference between the two files is an extra space on the end of the file that works. Looking in developer tools at the elements, the example that does not work the tooltip <DIV>s are inserted BEFORE the Treemap <DIV> and in the example that works the tooltip <DIV>s are inserted AFTER the Treemap <DIV> hence the z-index rendering differences. Who knew the power of a space :) Thanks for your help, Paul On Tuesday, 16 February 2016 20:12:03 UTC, [email protected] wrote: > > I am using a Treemap based on the Treemaps documentation utilising > the generateTooltip option with the 4 line tooltip example. > The Treemap displays as expected but the tooltips appear 'behind' the > Treemap.
