Clustering: Display Sum of Feature Values in Pop-Up

JasonUnger — Thu, 17 Oct 2019 19:31:58 GMT

Hi folks -

We have a data set whose individual features include numeric values and I'm trying to determine if we can calculate and display the sum of each feature's data when they are clustered together.

Specifically, we're tracking bombing incidents by location. With each bombing incident, one of our data points is the number of people killed.

When the incidents are clustered together, we can display the total the number of incidents and display the average number of people killed per incident (which, if we could just do math in the pop-up WYSIWYG editor, we could at least get a close to accurate total).

There does not appear to be a way to get the SUM of all the features' "number of people killed" data points and display that in the cluster pop up.

Is there?

Are we looking at this the wrong way? Is there some other way to show the SUM of the clustered features values?

Thanks in advance.

- Jason

Hi Jason,

Have you looked into writing an Arcade expression for the pop-up using the Sum function?

Hi Peter!

Thanks for following up.

Yes - even though I can write the custom expression, it isn't displayed as an option when developing the clustered pop-up.

After talking to ESRI staff, I was informed this capability is not supported -- it's currently a suggested idea.

I believe the sum function would be very useful.

In many cases mean has no sense and the correct statistics to apply is just the sum of a numeric attribute field values in the clustered features.

Please, implement it!
