In this post, I’ll show you how you can create segments without manually writing expressions.

Segmentation is a core activity in many visualization and analytics exercises, so making it easier is essential to being more productive. In Arcadia, you can create segments following these steps. This way, you manually enter the expressions in the Filters field in the Add Segment window. Alternatively, you can use the following trick to create a segment by saving a filter as a segment.

Dataset

We are working with the dataset SFPD Reported Incidents Since 2014 [data source]. The data shows the categorized number of incidents reported by the San Francisco Police Department in the year 2013. We will create four segments Q1, Q2, Q3 and Q4 for the year 2010.
