Segmenting with dimensions

Dimensions and measures affect visualizations differently; 

 - Dimensions are used to segment data

 - Measures can be aggregated

 

Segmenting: grouping similar data together

- eg. average price per room type 

 

 

Tableau automatically separates fields into data roles: Dimensions and measures.

Dimensions and measures affect visualizations differently. Understanding their differences will allow us to build visualizations faster and to collect the choices made by Tableau.
