analytics - 使用 Keen IO 创建给定时间段内 session 长度的直方图

Question

我们正在尝试构建给定时间段内 session 长度的直方图。目前，我们有 sess:start 和 sess:end 事件，其中包含 session ID 和用户 ID。我想知道计算这些数据的最佳方法是什么？这可以使用漏斗 API 实现吗？

你检查过recipes section in Keen IO's docs了吗？ ？以下是 session 长度直方图配方部分的摘录，可能非常有用。

摘录

To create a histogram for session lengths, like the one shown above, you can run a count analysis on an event collection for completed sessions (e.g. session_end). Along the x-axis you’ll have segments of time lapsed in a session, and along the y-axis you’ll have the percentage of sessions that fit into a given session length cohort.

Note: this recipe incorporates the D3 histogram recipe, which is explained further in the documentation.

histogram('chart-1', {
    segment_length: 60,  // In seconds
    data_points: 10,  // i.e. There will be 10 bars on our chart
    analysis_type: 'count',
    query_parameters: {
        event_collection: 'session_end',
        timeframe: timeframe,
        filters: []
    }
});
