Column Chart tasks without assignee

Hi @Niels_Oomen , Oh I see now what you mean.

Unfortunately, currently, Asana does not support ‘unassigned’ as a filter in dashboards.

You could then use this field in a dashboard’s chart, like this:

But since you want to see it by category and only unassigned tasks, you would set the X-axis to the custom field of your ‘specific category’ and then add a filter to only show the unassigned tasks from the ‘Assignee status’ custom field, which we created above, like this:
