This dialog is used to define the points that make up the head or flow pattern that is associated with a non-sinusoidal periodic head-flow element. The pattern is defined by creating Head or Flow vs Time points.

The New button adds a new row to the table; the Delete button removes the currently selected row from the table, and the Report button generates a preformatted report displaying the Time vs. Flow (or Head) data points for the Periodic Head-Flow curve.
