I found that the number value y (0.123456) gets rounded 2 decimal places (.12) when displayed the in the toolTipeContent {y}. Is there a work around for forcing the non-rounded value to display in the toolTipContent?
That issue has been fixed in the upcoming version – 1.2 beta. Though it’ll take some time for the public release, I can give you the latest version for testing – by monday.
