Tooltip before and after draw hooks not documented and weird behaviour

[LeeLenaleee]

Documentation Is:

• Missing or needed
• Confusing
• Not Sure?

Please Explain in Detail...

The tooltip plugin calls the following plugin hooks: beforeTooltipDraw and afterTooltipDraw. These don't seem to be documentated.

Also it seems like the hook are called in the wrong place because it seems they get called every render cycle. But changing this will make it a braking change.

Your Proposal for Changes

Document the plugin hooks.

Change the hooks to only fire when the tooltip is actually being draw instead of every render cycle

Thanks for adding this as a milestone. I am currently monitoring other lifecycle triggers and watching the chart context for changes in the tooltip. It would be more logical to trigger when the tooltip notifies the chart of changes directly.
