Highcharts - Gantt Chart plot issue
I want to draw gantt-like chart and using this solution . It works like a charm as long as I don't start to use big intervals. // Define tasks (unixtime * 1000) var tasks = [{ name: 'Eat', intervals: [{ // From-To pairs from: 1360800000000, to: 1360886400000 }, { from: 1360368000000, to: 1360454400000, }, { from: 1360195200000, to: 1360281600000, }, { from: 1361059200000, to: 1361232000000 }] }]; Here is my example , based on code above. If you hover your mouse over the interval you will see not quite what expected: it shows wrong tooltip from other interval. What's wrong with my code? May be
