Line charts for metrics dashboard

Problem to solve

We are working to add additional chart types to GitLab, and we therefore need a way to define which type you want for a given chart. We can start with adding this support in YML based definition and database schema, and then add the option in the UI when we build the chart designer: https://gitlab.com/gitlab-org/gitlab-ee/issues/4452

Also - we know additional teams at GitLab are also thinking about dashboards, and it would be great to build a framework which multiple teams can leverage, as well as users mixing and matching panel types.

This issue's scope covers line charts.

Intended users

• Delaney (Development Team Lead)
• Sasha (Software Developer)
• Devon (DevOps Engineer)
• Sidney (Systems Administrator)
• Sam (Security Analyst)
• Dana (Data Analyst)
