This is happening because [`timeUnits['millisecond'] > closestPointRange` is false](https://github.com/highslide-software/highcharts.com/blob/6ea3eb87a07ed44f91cbbc4cf06f43a6519d8f28/js/highstock.src.js#L9331) and [`lastN` is not initialized](https://github.com/highslide-software/highcharts.com/blob/6ea3eb87a07ed44f91cbbc4cf06f43a6519d8f28/js/highstock.src.js#L9318). I believe initializing `lastN = 'millisecond'` will fix the issue (works for me, at least)."},"comment":{"url":"https://api.github.com/repos/highslide-software/highcharts.com/issues/comments/105467330","html_url":"https://github.com/highslide-software/highcharts.com/issues/4223#issuecomment-105467330","issue_url":"https://api.github.com/repos/highslide-software/highcharts.com/issues/4223","id":105467330,"user":{"login":"vickychijwani","id":439616,"avatar_url":"https://avatars.githubusercontent.com/u/439616?v=3","gravatar_id":"","url":"https://api.github.com/users/vickychijwani","html_url":"https://github.com/vickychijwani","followers_url":"https://api.github.com/users/vickychijwani/followers","following_url":"https://api.github.com/users/vickychijwani/following{/other_user}","gists_url":"https://api.github.com/users/vickychijwani/gists{/gist_id}","starred_url":"https://api.github.com/users/vickychijwani/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/vickychijwani/subscriptions","organizations_url":"https://api.github.com/users/vickychijwani/orgs","repos_url":"https://api.github.com/users/vickychijwani/repos","events_url":"https://api.github.com/users/vickychijwani/events{/privacy}","received_events_url":"https://api.github.com/users/vickychijwani/received_events","type":"User","site_admin":false},"created_at":"2015-05-26T09:41:45Z","updated_at":"2015-05-26T09:41:45Z","body":"@highslide-software, tangential question: should I open a new issue if an option is undocumented in the Highstock reference but documented in Highcharts?
