Hi,
If the allocation is used at a higher (Feature) level and the issue count must be done at a lower level, the allocation should be inherited down from the feature to the stories. That is possible if Allocation is a single-value custom field.
This community post explains how to do that with a Javascript-calculated custom field in eazyBI: How to filter Portfolio hierarchy splitting by custom filed values - #2 by janis.plume.
Note that the configuration needs to precisely specify the hierarchy level ID, from which the value shall be updated. In your case, that is jpoh_parent_2.
This configuration will create a new dimension, and your report should give the pie chart by using this new dimension.
Kindly,
Janis, eazyBI support
