How can I display a daily timeline for two users in a Kendo UI Chart?


When implementing the suggested solution, note the following:

  • The time of the day is represented as a time span, relative to a fixed date—for example, 01.Jan.
  • Each slot has a unique ID.
  • To create one series per data site, the data source is grouped by ID. This is important because, normally, a series can have only one data point per category.
  • Categories are bound to model fields.
  • Series spacing is set to -1 (-100%), so that series can line up with each other. Normally, they are rendered one below the other.
  • Value axis labels are formatted to display the time of the day and are spaced one hour apart.

The following example demonstrates how to create a timeline by using range bars.

    <div id="chart"></div>
    var data = [{
        id: 1,
        user: "Jon",
        from: new Date("2014/01/01 11:30").getTime(),
        to: new Date("2014/01/01 14:45").getTime()
      }, {
        id: 2,
        user: "Joe",
        from: new Date("2014/01/01 09:30").getTime(),
        to: new Date("2014/01/01 09:45").getTime()
      }, {
        id: 3,
        user: "Joe",
        from: new Date("2014/01/01 10:00").getTime(),
        to: new Date("2014/01/01 10:15").getTime()
      }, {
        id: 4,
        user: "Joe",
        from: new Date("2014/01/01 12:00").getTime(),
        to: new Date("2014/01/01 14:00").getTime()
      }, {
        id: 5,
        user: "Joe",
        from: new Date("2014/01/01 15:15").getTime(),
        to: new Date("2014/01/01 15:30").getTime()
      }, {
        id: 6,
        user: "Joe",
        from: new Date("2014/01/01 15:45").getTime(),
        to: new Date("2014/01/01 16:00").getTime()

        dataSource: {
          data: data,
          group: {
            field: "id",
            dir: "desc"
        series: [{
          type: "rangeBar",
          fromField: "from",
          toField: "to",
          categoryField: "user",
          spacing: -1
        valueAxis: {
          min: new Date("2014/01/01 08:00").getTime(),
          max: new Date("2014/01/01 17:00").getTime(),
          majorUnit: 60 * 60 * 1000, // 60 minutes in milliseconds
          labels: {
            template: "#= kendo.toString(new Date(value), 'HH:mm') #"
        legend: {
          visible: false
