Using a custom field as a unit
Your number field custom fields can be used as a unit of a chart. For example, if you have assigned estimates for tasks (e.g. hours or story points) using a custom numeric field, you can select it as a unit for a chart.
Screenful will automatically make all numeric fields available in the Unit menu in the chart editor. If you have a drop-down field that you'd like to use as a unit, you can change the default field mapping.
Comparing multiple custom fields
What if you have multiple custom fields and you want to have all of them in one chart? Let’s assume you want to compare the values of three different number fields over time. You can do that by adding them one by one.
In this example, we’ll use the multi-bar chart. Pick one of the custom fields as the unit for the chart. After that, use the Add custom field button to add the other two fields.
Here’s the final chart with three custom units, grouped by week:
The unit shown on the left axis will be the field that was selected first. You can rename the unit to whatever you like it to be in the Chart format section.
Grouping and filtering by a custom field
Custom fields that are of type drop-down become available in the group by menus so you can use them for grouping data in the chart:
Here’s an example bar chart using a custom field as unit (work left), and another custom field (component) for grouping:
Drop down fields can also be used in filtering the chart. To access the filter feature, click the Set filter button in the chart editor to open the filter window. Your drop down custom fields can be found at the bottom of the list:
Once you save the filter, the chart is filtered by that custom field.
