I have a hierarchical xml file. To start with I got all root level children and created a data structure for PolarArea as listed in the documentation.  I added few additional parameters to the data structure but when I get the activePoints object on click the additional parameters are missing.\r\n\r\ne.g: \r\n\r\n```javascript\r\n     var data = [ {'extraval': 'some_uid', 'label': label, 'value':  value, 'color': color, 'highlight': high_col}, ... ]\r\n     myNewChart = new Chart(ctx).PolarArea(data);\r\n\r\n     canvas.onclick = function(evt){\r\n\tvar activePoints = myNewChart.getSegmentsAtEvent(evt);\r\n\tdrilldowndata(activePoints);\r\n    };\r\n\r\n    function drilldowndata(ap) {\r\n\tconsole.log(ap);\r\n    }\r\n````\r\n\r\nso when I print ap object extraval is not available.  \r\n\r\nAny thoughts perhaps I am missing something\r\n\r\nThanks\r\nJay\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/nnnick/Chart.js/issues/comments/108734666","html_url":"https://github.com/nnnick/Chart.js/issues/1050#issuecomment-108734666","issue_url":"https://api.github.com/repos/nnnick/Chart.js/issues/1050","id":108734666,"user":{"login":"tannerlinsley","id":5580297,"avatar_url":"https://avatars.githubusercontent.com/u/5580297?v=3","gravatar_id":"","url":"https://api.github.com/users/tannerlinsley","html_url":"https://github.com/tannerlinsley","followers_url":"https://api.github.com/users/tannerlinsley/followers","following_url":"https://api.github.com/users/tannerlinsley/following{/other_user}","gists_url":"https://api.github.com/users/tannerlinsley/gists{/gist_id}","starred_url":"https://api.github.com/users/tannerlinsley/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/tannerlinsley/subscriptions","organizations_url":"https://api.github.com/users/tannerlinsley/orgs","repos_url":"https://api.github.com/users/tannerlinsley/repos","events_url":"https://api.github.com/users/tannerlinsley/events{/privacy}","received_events_url":"https://api.github.com/users/tannerlinsley/received_events","type":"User","site_admin":false},"created_at":"2015-06-04T05:42:24Z","updated_at":"2015-06-04T05:42:24Z","body":"That could work.\nOn Wed, Jun 3, 2015 at 11:41 PM Derek Perkins <notifications@github.com>\nwrote:\n\n> How would you feel about making a new array called userData across all\n> config types so there isn't any chance of conflict?\n>\n> —\n> Reply to this email directly or view it on GitHub\n> <https://github.com/nnnick/Chart.js/issues/1050#issuecomment-108734115>.\n>\n"}}
