The following steps demonstrate how to create a new data segment by cloning an existing one.
On the main navigation bar, click Data.
The Data view appears, open on the Datasets tab.
Find the dataset in the list of datasets, either by scrolling or by using search, and click on it.
We are using the dataset Flight Delays.
In the side navigation menu, click Segments.
In the Segments list, find the segment to clone, and click Clone.
In this example, we are cloning Delayed Flights.
A pre-populated Add Segment modal window appears.
Edit the Add Segment modal window by changing its entries.
Under Filters, leave the first line filter as is, but change the second filter to the following content:
[dep_delay] <= 0
The new segment definition appears in the Segments interface.
Note the similarity in the definition of the two filters, Delayed Flights and On-Time Departure.
