above and below mapping styles

The above and below mapping option is taken to another level with the ability to combine colour and unique symbols to emphasize the values above or below a threshold in the new MapViewer. Same functionality and mapping style to ArcGIS Pro.

ArcGIS Pro offers a number of diverging color schemes. I see 90 when I do a quick search:

These can be applied and adjusted as needed to symbolize "above and below" some meaningful value:

Currently in Pro, the workaround is to set to unique values and apply an Arcade expression like:

when
($feature.FieldName<FieldAverageValue,1,0)

The average value in the expression can be get from show statistics if apply graduated colors or graduated symbols using this field.

E.g. my expression is:

Then you will have binary symbol pair in the grid and can change its style:

Then use the second tab on the pane "Vary symbology by attribute" to add size or color variable.

@KoryKramer I'm hoping to do something similar to what you described but with unclassed colors. Is this possible? I don't see the option to set a middle point for the diverging color schemes.

To me this matters because when symbolizing by proportional symbols and adding additional symbology by color there is not an option for classes.
