Tooltip: Would like all column ranges in a series to be highlighted when mouse hovers on one element
I wish there is a way to load images so I can show you a screenshot. Now I'll try to describe it: Say Joe and Bob eat fruit apple and pear and Joe's consumption is green colored. I want the tooltip to do this: When the mouse is placed on Joe's share (a green area) in either apple or pear category, the tooltip shows Joe's consumption of apples AND pears (like apples: 2, pears: 5). That's easy using the "formatter". However, I also want Joe's shares (the green areas) in BOTH apple and pear categories to be highlighted. Currently, only the green area under the mouse is highlighted.
So you're looking to display multiple tooltips at the same time? Or will http://api.highcharts.com/highcharts#tooltip.shared help you?
In the image above, I'd like to have all blue bars highlighted, because they all belong to the same application that is running on multiple machines.
