A Count or Sum of Cards will give you a quick at-a-glance count of Cards or Sum of a custom field value across a selection of Cards.
Create a new chart.
Select "Count of Sum" from the menu options.
Select which Cards you would like to count.
Select the Board from which you would like the Card count. Hit "Continue" or press enter.
Now you can choose to apply a filter or not. Filters can be edited on the report after should you decide to view your data differently.
Note: If you have selected to report on Completed Cards we recommend the "No Filter" option as a default.
If you have selected to report on Open Cards we recommend adding a filter for Lists to only show the Open Cards in the Lists you are interested in. For example you may only want to show cards in your 'Doing' Lists...
Give your count a name. Hit "Save" or press enter.
Once you're count is complete you can do the following:
Hover your mouse over different parts of the chart to show further details on your specified data.
Drag and drop this chart tile anywhere you like within your dashboard.
Drill down (by clicking on the chart) and see full details of completed Cards and the time they took.
Note: Drilldowns are only available once you click 'Done' in the top right.
