High everyone,
I am trying to get three things to happen. First, I want to create a custom tooltip for a columnrange-type series where the tooltip shows something like HIGH: 'this.point.high' and on a new line "LOW:" 'this.point.low'. Second, I would like these 'low' and 'high' values to populate a form field dynamically. For example, when a user drags the high value for the columnrange entry, I want this to dynamically update a number in the corresponding formfield that collects user input.
Here is a fiddle: https://jsfiddle.net/e9zqmy12/
