Remaining Estimated Hours History - fix

Hello,

I hope everyone is keeping well !

I am trying to get my remaining estimate hours history measure (or different calculated measure) to take into account hours spent on sub-tasks so that my burndown chart is showcasing data right.

As you can see below I have 10.5h then 6h from sub-task and then my remaining hours are still 10.5h - which makes my burndown chart not correct.

I am trying to create a burndown chart using - Time Tracking Burndown in Selected Sprint - Issues - Jira Demo - eazyBI
