Hi
I would like to ask a question regarding to data type of the retail analysis sample that I downloaded from this power BI website
https://powerbi.microsoft.com/en-us/documentation/powerbi-sample-retail-analysis-take-a-tour/
The picture shows the list of fields/measures. There is a traffic signal icon on the bottom of the list where it says "This Year Sales". Could someone tell me what this is and how this works/ how it was made?
Similary, this is also from same sample data. On the top of the fields list, there is icon where it says "Date".
Please describe what it is and how this works/ how it was made. Thank you!
