Sorting chart data
Sorting makes sure your CHARTS have more relevant data on the top.
Placing a minus ( -ga:metric) preceding to the metric you want, will sort data in decreasing order and placing the metric alone (ga:metric) will sort data in increasing order.
Consider an example of a widget with: Users vs Source/Medium TABLE
(1) adding -ga:users will sort in decreasing order i.e. source/medium with most visitors will be added to top of the table.
(2) adding ga:users will sort in increasing order.
When using max. Results field make sure you use SORT too so that more relevant data will come within max. Results you specify.
