On your Jira Cloud instance, navigate to your Project settings or Project settings > Apps for team-managed projects.
On the left menu, choose Issue Matrix Configuration.
On the Issue Matrices page, click the Add Matrix button.
From the list, choose the Epic Matrix type.
On the Add Matrix page, you can set configuration options to build the matrix panel you want to see in your issue.
Context > Linked Projects: Choose the projects where you want the matrix panel to appear. By default, the Issue Matrix configuration is linked to the current project only. If you add more than one project in the Projects to link field, you will create a multi-project configuration. The Issue Matrix configuration and panel will appear in all linked projects.
With multi-project issue matrices, changes to the Issue Matrix configuration in one of the projects will affect the rest of the projects.
Type > Issue Types: In this section, choose issue types, linked to the current epic that the Issue Matrix panel will show.
Data: Configure the data (columns, their width, and headers) the Issue Matrix will show. The columns are custom fields from your Jira Cloud instance. The value of the custom field for a given issue will be visualized in the panel.
Sort By: Set a default order for the data displayed in the matrix by choosing one or more fields in the Sort By section.
Save the configuration.
