Time Series Analysis

Summary: Time series analysis allows you to plot metrics over time using time intervals such as Monthly or Yearly. You can also use date filters to easily filter for a specific date period.

Time series analysis shows the trend of metrics over a time interval in the X axis. With Answerdock, you only need to put the metric( e.g. sales) and the interval (e.g. monthly) to start with your Time Series Analysis. You can also add a date filter and a secondary dimension to your question or search. Below is a quick explanation of time intervals and date filters.

Time intervals

Time intervals group dates falling into specific time intervals together to create a date dimension. You can use any of the following to denote a time interval:

By Minute Quarterly By week of month
By second Yearly By week of quarter
Daily By day of week By week of year
Weekly By day of quarter By month of quarter
Monthly By day of month By month of year
Hourly By day of year By quarter of year

By default, time intervals default to the primary date set for the dataset in the settings page. If you have more than one date field in your dataset, you can change this date by two methods.

1- Lookup the correct time interval to the specific date from the search guidance menu

2- Type the date field that you need the interval to relate to next to the time interval

Note that AnswerDock supports fiscal calendars, and you can edit the properties of any date column in your dataset to make it refer to a fiscal calendar with a start date other than Jan 1st.

Date filters

In Time Series Analysis, date filters can come handy. There is a complete section in this chapter regarding filters. In summary, you can type almost any date filter you can think of and AnswerDock will be able to understand it. A few examples are as below:

  • Last year, this quarter, month to date
  • After may 19 this year
  • 5/13/2008-6/14/2017
  • before 11/20/2017
  • from jan 1 2018 to may 14 2018
  • last 7 days
  • 2 months ago
  • Last x days including today
  • Last y months including this month
  • This month exclude today
  • starting jan 2017 and ending february 2018
  • Q1 2018
  • January 2017
  • 2013-2018
  • etc…

You can also see more examples of date filters in the Keywords Reference Guide

Example of Time Series Analysis

Using Two Interval Keywords

Using two interval keywords gives you an interesting look at the evolution of performance over time. For example, you can ask:

  • Sales Monthly Yearly

This will Plot the sales for each month, represented by different lines for each year.

Double Interval Question

You can ask different variations of the above question, such as:

  • Sales Monthly quarterly
  • Sales Daily Yearly
  • Sales Weekly monthly
