Render chart tooltips in the same way as standard tooltips (#1745)

Browse Source 
* Render chart tooltips in the same way as standard tooltips

* Move OpenChartTooltip method to TooltipService to avoid code duplications

* Avoid partially hiding of chart tooltip near top of page

* Make some of the types internal.
