Hi,

I am using the tooltip controller that triggers immediately when the mouse cursor passes over a line. The problem is that for a split second you can see there is a small tooltip box that has no content that appears before the real tooltip box appears. I was wondering if there was a way to make that empty tooltip box not appear. I am sending a project reproducing this situation.

Also I  wanted to know if there was a way customize the appearance of the tooltip controller. Specifically to make the border color of the tooltip match the color of the series that is displaying the tooltip.

Thanks in advance!
