The Year-Over-Year Viewlet provides a side-by-side comparison of the monthly value of up to two variables, such as energy consumption, over multiple years for one or more selected months. The dual axis setup allows for different variables at different locations to be plotted against one another. This is useful for a quick analysis of year over year trends by the month.

The scale of each axis is different, so be sure to understand the true value for each variable. Rollover pop-ups help identify the trends.

Year-Over-Year Drilldown

Clicking on the individual trends will open up a smart chart drilldown menu. Clicking on the graph type will open up a new Dual Axis viewlet of that specific trend.

If there are rolled up trends being shown in the Year-Over-Year viewlet, the user can drill down into the trend hierarchy instead of always drilling down into the time range like above.  This feature can only be used with rolled up trends (ones created in PersicopeConfig using the "rollup" feature).  The new options are:

  • Ranking - Creates a new Ranking Chart with all children trends (only available in Ranking Charts)
  • Stacked Column - Creates a new column chart with stacked columns
  • Multi-Line - Creates a new Line Chart

Year-Over-Year Configuration

There are four tabs in the Year-Over-Year Viewlet’s configuration menu. The first two are for filtering the trends by unit and/or location, and selecting which variables which will be on each Y-axis. The user can choose the months and years which will be compared in the “dates” tab, and normalization and rollups are specified in the “options” tab.


Axis 1 & 2:

You can select a single trend by filtering Locations or Units, or both. Additionally you can start typing in the trend name in the search box to narrow down the search field. The Units are dictated by the global properties inside Periscope Config. 

Dates:

Select which months and years to be displayed. 

Options:

Normalize axis 1 & 2 and set the rollups to sum, min, max, or average.
