How do I change the constraints on historical time parameters in gadgets?

A number of JIRA gadgets show historical data from your JIRA instance. You can generally configure the time constraints on this data via gadget parameters, i.e. how far back should data be retrieved? However, there are also JIRA-level constraints on how far back you can specify data to be retrieved, for performance reasons.

For example, the 'Time Since Issues' gadget allows you to specify how far back issue data should be retrieved via the 'Days Previously' parameter. However, if you try enter a value greater than 300, a validation message will display and you will not be permitted to save your configuration changes.

The fields that are used for these validations can be found in your jira-application.properties file in your JIRA installation directory:

jira.chart.days.previous.limit.yearly=36500
jira.chart.days.previous.limit.quarterly=22500
jira.chart.days.previous.limit.monthly=7500
jira.chart.days.previous.limit.weekly=1750
jira.chart.days.previous.limit.daily=300
jira.chart.days.previous.limit.hourly=10

To update these fields, simply locate them in jira-application.properties, update as desired, save your changes and restart your JIRA server.
