The Overview console has three sections, Submission Volume, Submission Breakdown, and Recently Updated. Data is limited to the currently selected Kapp.
This graph breaks down submissions by all Forms by day. Number of days (30, 60, 90) can be changed in the dropdown in the upper right. Hovering over one of the nodes on the graph shows the number of submissions for that day.
This graph shows volume of submissions by form. Forms in the selected Kapp are shown with a percentage of submissions and a pie chart representation.
