Priority of aggregations

In the scenario, “Top 5 cities with the highest weekly temperature over the last 90 days”  can be interpreted two ways:

Option 1: Top 5 cities with the highest average of temperature over last 90 days, displaying theirs temperature each week.

Option 2: Each week’s top 5 cities with the highest average of temperature, displaying the temperature each week for the last 90 days.

See the differences between these two options below.

Option 1:

In the Buckets panel, the city.keywork has higher priority than timeStamp.

The chart result shows weekly temperature of only 5 cities that have the highest temperature over the last 90 days.

Option 2:

In the Buckets panel, change the timeStamp to have higher priority than the city.keyword.

The chart result includes weekly temperatures of different cities. The top 5 is different week-to-week, so there are more than 5 cities in the legend.
