how to handle tooltip refresh event?

[ying]

Hi,

From your source code the tooltip will fire a refresh event every time it refresh its content and position. However from my test, looks like it is not fired. Is there any thing wrong with my code?

Hi ying,

In docs, there is no something like tooltip.events.refresh. If you want to fire a function every time the tooltip is shown, I suggest using point.events.mouseOver event: https://api.highcharts.com/highstock/pl ... .mouseOver

If it doesn't meet your requirements, please provide me more details about what do you want to do, and I will suggest another approach.

Best regards!

Hello ying,

You can handle tooltip refresh event via working on Tooltip.prototype. Check below demo:

Kind regards!

you basically copy paste the original refresh function of H.Tooltip in highcharts.src.js. just curious why the one in the highchart.js is not working with the fired event,(why can not catch the event?) but have to define the refresh function again with customized handling -- your alert message

Inside tooltip object, you can set options which should be triggered from the core. Notice that tooltip.events it's not defined in the core. I showed you a way how to 'get inside' the core to do some changes.

Here is a demo which should help you to understand what I am talking about - look into developer console after hovering some point:
