how can i use part of original estimate base on weekly period in workload chart

[Ali Shadroo]

i have a workload pie chart and i want to see the original estimate per asignee on weekly bases to forccast the load on project.

e.g i have two task one takes 12 day and other one 14 day, but in my workload chart it shows 26 day instead of 10 day for first week.

any idea how to mange the JQL to calculate workload for each week base on the total estimation?

Thanks
