We would like to be able to see in one stacked column/bar the combination of two data groupings... ex first category group (=name column) with as subgroup phase mentioning for the items in this category (stacked items in the column by category). Currently not possible to see this in the chart widgets. Solution offered is to add Report Widget to show grouping but this is not good enough as visual.
Feel free to reach out in case more info is needed, related to case 06274533
