间隔事件的交互式时间线图[标签；开始：结束]数据？

Question

我是 JS 的新手。我想可视化每个事件定义如下的时间间隔数据：

[label; start time: end time]

标签：字符串和开始/结束时间以毫秒/微秒为单位

我可以使用 Google Timeline 可视化来可视化这些数据：

但我想为此添加一些其他属性。因为我的间隔数据将以毫秒为单位。

• 我想让网格间隔让我们说一些 x 值。
• 标记 X - 轴如 0----5----10----15
• 缩放选项：类似于我们在 Google AnnotatedTimeLine 中的功能。由于给定的行可能有数千个事件，我们有兴趣分析给定时间范围 [2200ms-2500ms] 内的详细信息。

我们如何在 TimeLine 中设置缩放选项，如上图所示（AnnotatedTimeLine）。

简而言之，我在 Google TimeLine 包中寻找类似 Google AnnotatedTimeLine 的设施。我该怎么做？

由于我们的数据是区间数据（不是时间序列数据），我们不能使用 AnnotatedTimeLine 可视化。

任何帮助将不胜感激。 :)

Answer 1

首先，没有任何configuration options 可以控制 x 轴标签
它们在绘制图表时动态设置，并根据显示的时间范围而变化

接下来，annotation chart 上的缩放选项可用作任何图表的控件

ChartRangeFilter 可以使用Dashboard 绑定到图表

（改编自另一个答案）

google.charts.load('current', {
  callback: drawDashboard,
  packages: ['controls']
});

function drawDashboard() {
  var dashboard = new google.visualization.Dashboard(
    document.getElementById('dashboard')
  );

  var control = new google.visualization.ControlWrapper({
    controlType: 'ChartRangeFilter',
    containerId: 'control',
    options: {
      filterColumnIndex: 3,
      ui: {
        minRangeSize: (60 * 60 * 1000),
        chartType: 'TimeLine',
        chartOptions: {
          width: 900,
          height: 70,
          chartArea: {
            width: '100%',
            height: '80%'
          },
          hAxis: {
            baselineColor: 'none'
          }
        },
        chartView: {
          columns: [3, 4]
        }
      }
    }
  });

  google.visualization.events.addListener(control, 'error', function (error) {
    console.log('error: ' + error.id + ' - ' + error.message);
    google.visualization.errors.removeError(error.id);
  });

  var chart = new google.visualization.ChartWrapper({
    chartType: 'Timeline',
    containerId: 'chart',
    options: {
      width: 985,
      height: 600,
      chartArea: {
        width: '100%',
        height: '80%'
      },
      tooltip: {
        isHtml: true
      }
    },
    view: {
      columns: [0, 1, 2, 3, 4]
    }
  });

  var data = new google.visualization.DataTable();
  data.addColumn({ type: 'string', id: 'Student' });
  data.addColumn({ type: 'string', id: 'Event Type' });
  data.addColumn({ type: 'string', role: 'tooltip', 'p': {'html': true}});
