Adding dates to Trello cards
You can set start and due dates in Trello by clicking the Dates button within an individual card.
You can set the due date by selecting the date and time from the calendar. You can set a start date to a card by checking the "Start Date" box and selecting the date.
You can also use any of your custom Date fields to represent the start dates or due dates. Learn how to configure any custom date field as start or due date for tasks.
Notice that there may be some delay before the dates become visible in the Screenful. Once you have set the dates, they will be reflected in the chart after the next data sync which is run automatically once per hour. You can trigger the sync manually any time by selecting Data sync options from the main menu.
Configuring the Workload (planned) chart
To create a Workload (planned) chart, go to the Charts tab and click Add new chart.
A modal is opened with a set of chart templates. Select New blank chart to open the chart editor. Select Workload (planned) as the chart type. In this example, we’ve selected grouping to be by Week, and bar segment to be Assignee.
That produces the chart seen at the beginning of this guide:
Notice that you can use any of your custom fields as the unit. By default, the chart uses Tasks, as the unit but you can change it to any of your custom fields from the unit menu. So for example, if you have set work estimates to your cards (e.g. as Story points), you can configure the chart to use those.
