Range selector in PA widgets displays one additional month - Known Error

Range selector in PA widgets displays one additional month 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:

Run the data collector for incident "Number of open incidents" for the last 180 days 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.
