I am using ChartJS 2.0 to display alarmed and non alarmed images for an event (this is a home security app). In a typical event of  say 100 frames,  'alarms' will have a non 0 score, whereas normal frames will have a 0 score.\r\n\r\nI am displaying a graph with a toggle option. toggle=\"alarms\" only displays alarmed frames (i.e. frames with a score > 0) while toggle = \"all\" displays all frames (including frames with a score = 0)\r\n\r\nI am then allowing the user to touch and drag around the graph to conveniently see all the frames.\r\n\r\nThe problem I am facing is that when I am displaying all frames in a bar graph, the frames with a y axis value of 0 (score) don't show a bar at all. Which is understandable. However, I do want them to show as a bar (I can't add a value of 1 to the score as that is misrepresentation). Rather, I thought I'll compromise and start the y-axis with '-1' so I expected values of 0 to show a bar.\r\n\r\nBut this is what happens: as I drag my finger/mouse around, I see the hover tooltip, but the bars still start drawing from 0, not -1.\r\n\r\n<img width=\"189\" alt=\"screen shot 2016-04-02 at 1 12 20 pm\" src=\"https://cloud.githubusercontent.com/assets/4116654/14227924/ba51d2d4-f8d5-11e5-8d58-a4fbfbd568ef.png\">\r\n\r\nMy options:\r\n```\r\n options =  {\r\n          \r\n        scales: {\r\n            yAxes:[{\r\n                ticks: {\r\n                   // beginAtZero:true,\r\n                    min:-1,\r\n                },\r\n            }],\r\n            xAxes:[{\r\n                display:false\r\n            }]\r\n        },\r\n```\r\n\r\nthank you."},"comment":{"url":"https://api.github.com/repos/nnnick/Chart.js/issues/comments/205002075","html_url":"https://github.com/nnnick/Chart.js/issues/2207#issuecomment-205002075","issue_url":"https://api.github.com/repos/nnnick/Chart.js/issues/2207","id":205002075,"user":{"login":"pliablepixels","id":4116654,"avatar_url":"https://avatars.githubusercontent.com/u/4116654?v=3","gravatar_id":"","url":"https://api.github.com/users/pliablepixels","html_url":"https://github.com/pliablepixels","followers_url":"https://api.github.com/users/pliablepixels/followers","following_url":"https://api.github.com/users/pliablepixels/following{/other_user}","gists_url":"https://api.github.com/users/pliablepixels/gists{/gist_id}","starred_url":"https://api.github.com/users/pliablepixels/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/pliablepixels/subscriptions","organizations_url":"https://api.github.com/users/pliablepixels/orgs","repos_url":"https://api.github.com/users/pliablepixels/repos","events_url":"https://api.github.com/users/pliablepixels/events{/privacy}","received_events_url":"https://api.github.com/users/pliablepixels/received_events","type":"User","site_admin":false},"created_at":"2016-04-03T15:51:10Z","updated_at":"2016-04-03T15:51:10Z","body":"Sounds good @etimberg  - look forward to trying out the zoom/pan future when you think its ready for beta consumption!
