To generate a Sprint Burndown Chart using VisualScript, you'll need VisualScript installed on your Jira or Confluence instance. Once VisualScript is added to your instance, you can find all the built-in reports as either gadgets to be added to a dashboard in Jira or macros to be used on a page in Confluence.
Choose the Sprint Burndown Chart report to add to your page or dashboard and click "Run." You'll be asked to provide a project key and sprint name and specify whether you want to include storypoints or not.
If you choose to track story points, make sure all issues in your selected sprint have story points assigned to them.
Once your Sprint Burndown is generated, you'll see a green line sloping from left to right that represents your ideal trajectory for progress.
The numbers in yellow boxes indicate the number of issues at the start of the day. The numbers in the yellow boxes indicate the number of issues completed that day. If you're using story points, the numbers will indicate story points instead of isssues.
The percentages to the left of the chart indicate the percent of work complete for the entire sprint.
The target burn rate is the amount of work that needs to be completed per day to complete all work by the end of the sprint. The actual burn rate represents the speed at which your team is actually getting through work.
Your team's velocity is the actual burn rate. This will let you know how much work they'll finish during the sprint.
