Jira Task (Epic) & Subtask totals in chart

[Dan Regan]

Hello Everyone,

Hope all is well

I am looking for a way to program a page in confluence to show in a chart the total time a Jira Task (Epic) has been open.  Also the total amount of logged time for all sub-tasks under that epic.  This has to be possible without buying an extra program.

I have tried a few different tools in confluence but can’t seem to get this data to show up in a chart so I can make a bar graph from that.

Something similar to this is what I am looking for:

Thank you
