One of our current approval processes in Forms has a lot of different approvers and some of those approvers have other 1,000 tasks at any given time. This causes some issues when looking at the Workload report for users that only have a couple of tasks to approve because the bar in the chart is not visible to click on (see screenshot).

If the number above the bar was clickable that would still allow the end user the ability to select that users tasks. Another option would be making the user's name clickable.
