Range selector in PA widgets displays one additional month

KB Summary by Now Assist

Description

When using the range selector to choose a specific time range to display on widgets, one extra month is displayed.

For example:

Selecting 3m in October (1st Jul - 1st Oct) would display any data that exists for July, August, September & all of October.

 

This affects all releases as it's related to a 3rd party charting library.

Steps to Reproduce

In a new instance:

  1. Run the data collector for incident "Number of open incidents" for the last 180 days
  2. Go to dashboards, and add a widget with the following field values:
    • Indicator: Number of open incidents
    • Type: Time series
    • Visualization: Column chart
    • Time Series: By month SUM
    • Date Settings > Period: 3m
    • Date Settings > Show date range selected: checked

Results are displayed for the previous 3 months as well as the current month.

Workaround

This is a limitation of the charting library that we use (Highcharts) and does not fall under our internal development scope. The chart will display data for the 'cut-off' month as well as the three previous months.

A bug was filed with the developers but was later closed:
