Forge allows developers to add custom fields that result in simple values but Forge-based fields are not available within Atlassian Analytics. I'd like to see at least simple Forge-based fields become available.
e.g. I define a Forge field similar to the following.
jira:customField:
- key: jira-interest-field
name: User Interest
description: A custom field to render user interest.
type: number
function: interest-view
value:
function: interest-value
Note: I cannot add this as a suggestion within the Analytics Jira site as the project does not show up for me when creating issues (other projects do).
