Show the last 20 sprints in the Sprint velocity chart

How can I set-up the sprint velocity chart to show the last 20 sprints?
The report show all the closed sprint, since we started use JIRA, December 2019.
I’m researching a configuration to set-up, to show the the last 30 or 20 sprints without need to edit the report in the future.

Hi Renato,

We have created a dashboard with various Sprint reports in the eazyBI Demo account here:Sprints Overview - Jira Demo - eazyBI.
You can find some ready-to-use examples and also some ideas for your reports.

We also have step-by-step instructions for creating a sprint velocity chart with the option of limiting the number of sprints here: Sprint velocity chart.

Chart users may then select the desired number of sprints to be displayed.

Please let me know if it works for you!

Kind regards,
