I have this sample https://jsfiddle.net/totszwai/4g7uxdfL/
I tried to make the column like, scale(2) + translateY, or something on hover, but I'm having a hard time to scale it up and shifting it back to the correct position... Is there an easier solution to make the bar "pop" on hover? I must've been doing it the wrong way... but I tried to use out of the box API from Highcharts such as markers, states etc and couldn't archive the results I wanted.
