xCharts is a charting app that allows generating custom charts & reports directly within Jira to visualize projects and issue analysis. New charts can easily be created in no time by using chart & report templates. Furthermore, these templates can be expanded by just scripting your own charts using Groovy and Javascript.
After installing xCharts, a charts tab will appear on your Jira's navigation bar:
