"Default impedance values indicating the extent of the service area to be calculated. The default can be overridden by specifying the breaks value on the facilities.
Multiple polygon breaks can be set to create concentric service areas. For instance, to find 2-, 3-, and 5-minute service areas for the same facility, specify "2 3 5" as the value for the Default break values parameter (the numbers 2, 3, and 5 should be separated by a space)."
but in rest api 5 minutes not meet real result. when i add polygon of service area on my map it is drawing so little area... to accomplish this i multiplication 5 minutes with 100 for getting correct result...
my breaks_length : 10 polygon distance :100 outsr : 3857
