Symbolizing features with multiple attributes

Anonymous User — Thu, 29 Sep 2022 22:01:44 GMT

Hello esri community,

I am trying to highlight chemistry sampling data for my organization. Each station point has several "chemistry analytes" that needs to be displayed. Different sampling labs measure different analytes for each station.

I want to display the data in a way so that my organization knows which analyte has NOT been sampled.

My question is, is it possible to display what chemistry parameters are missing using pie / bar chart symbology given the current data table I'm working with? Can I accomplish this using any type of Arcade expression? I just want to understand how to best approach this.

Attached is the data table I'm working with, a screenshot of my work so far, and a screenshot of an ArcMap bart chart symbology that I would like to emulate.

Best,

Mina

One possible way:

set the layer's definition query to remove all parameters you don't want to show
create a symbol that shows text next to a colorable symbol, save to style
apply that symbol to your layer
enable symbol property connections
change to the text element, set the text string to the parameter field
change to the symbol element, set the color to the Arcade expression

var status = $feature.submissionstatus if(status == "complete") { return "green" } if(status == "rejected") { return "red" } return "grey"

change to the complete symbol, set the y offset to the Arcade expression

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

apply

You could of course also include the lab in the text by using your label expression instead of parameter. And you could also color the text by applying the color expression to the whole symbol instead of only to the symbol element:

Hi @Johannus ,

This was exactly the type of workflow I was looking for! I found your post to be exceptionally insightful and informative. I definitely learned a few new things along the way. Thanks a ton!

Hi @JohannesLindner ,

Your workflow worked great in ArcPro! Yet, when I tried to upload the layer as a web map, the arcade expressions used were not honored. I have worked on revising the web map on both the newer version and map viewer "classic", but I have yet to reach the same symbology.

Attached below is a screenshot of how I'm using your code, for your reference.

Any help or guidance here on how to best approach this would be greatly appreciated!

Best,

Mina

Huh. Try publishing the layer as web image layer / feature layer. That works for me in both Map Viewer versions. I use Portal, it might be different for AGOL.

As far as I know, the symbol options in Map Viewer are pretty basic, so you probably won't be able to configure that symbology online. I could be wrong though, as I configure everything in Pro before publishing.
