I\'ve been working at this for some time now. I\'m using Selenium and WebDriver version 2.33 (with all browsers). I\'m using Java, which should be arbitrary. What I\'m doing
From your discussion with Amey i deduced that you have only one highchart. so try directly searching for element "highcharts-tracker" using classname i.e By.ClassName("highcharts-tracker") and then hover on this element itself. This would exactly do what you want to achieve.
