This chart displays number of steps assigned to each Assignee, within the given period.

View mode can be switched (1) to highlight the late steps by Assignees (and chart will be named "Assignee Late Tasks").

Step numbers are shown as stacked bars of different colors:

• Active (2) - yellow
• Completed (3) - green
• Active and Late (4) - red

Step number bars can be sorted by descending (default) or ascending order. Click order button (5) to switch it.

Assignees displayed can be filtered to show only necessary. To make assignees filtered click Filters button (6), specify  and apply necessary filters criteria.

Filtering is simple enough. Assignee filter has a picklist with "contains" and "does not contain" operators, and multi-select lookup where several assignees can be selected. After filter is applied chart will show only assignees matching it:
