Hello GIS stack exchange community,

I'm trying to create a web map that highlights chemistry sampling data for my organization. Each station point has several "chemistry parameters" that needs to be displayed in a "bar chart" format.

The issue I'm running into is that the arcade expression I used in ArcPro where I created this map is not being honored once it's shared as a web map.

My question is, is there a process / workflow to include an arcade expression for modifying symbology? I just want to understand how to best approach this.

Attached is the data table I'm working with, a screenshot of my webmap, and a screenshot of the ArcPro symbology that I would like to re-create for the web map. The arcade expression that worked on ArcPro was this (using the symbol property connections)...

var offsets = {
        "Chlorinated Hydrocarbons": 0,
        "Inorganics": -10,
        "PAH": -20,
        "PCB": -30,
        "PBDE": -40,
        "Pyrethroid": -50,
        // and so on
    }
    return offsets[$feature.parameter]
