Manual Classification Method in ArcGIS Online when changing Symbols to color

Idea created by simo Champion on May 28, 2014
    when changing the symbols of a polygon layer to "use color" in the map viewer in AGOL, in the classification method options, AGOL only provides Natural Breaks, Equal Intervals, Standard Deviations and Quantles. these classification often give you a not-easy-to-read (for ordinary people) break values like "2324546 - 5657443".

    a manual method will help to create a clean and more meaningful classification like "2,000,000 - 5,000,000", which has been in ArcMap for a long long time.

    If ESRI serious about making a useful map (I am not talking about a sophisticated map with professional standard) online, this is a must-have feature.
