map zoom level when clicking on item list

Is it possible to set the map to zoom to a particular level when clicking on an item in a list?

For polylines and polygons, the app zooms to the extent of the feature.

For points, there is a "pointZoomScale" property that can be added/modified in the dashboard json (via AGO Assistant or other) to set a specific zoom scale. This property is not exposed to the dashboard creator at this time and must be manually changed in the json.

The app currently defaults to 10,000. So setting this property to a value like 1,000 will allow the map to zoom in more. The setting is per-webmap.

Make sure to have the correct capitalization or it will not respect the parameter:

"pointZoomScale"

thanks this worked, however my JSON did not have this parameter to begin with, I had to add it.

Correct, this is a parameter that we had to add to this JSON, it was not already there.

I want to zoom to a polygon (buildings) and show some of the surrounding area for context. Is there a polygonZoomScale property too? I tried it but nothing happened.

How do you get to the dashboard json in order to modify this parameter?

Hello Matt,

You can use ArcGIS Online Assistant to get the Dashboard's JSON. However, please be careful when editing the JSON configurations as it could cause errors with the Dashboard. It is recommended to save a copy of the Dashboard, rather than editing the actual Dashboard.

Best,

Aaron,

I would like to do something similar for an Operations Dashboard category selector Action = Zoom.

My OD map has a polygon selector based on Council Districts. It works fine but the zoom threshold is so large as to almost be not helpful.

I see all of the configurable Action filters, in the JSON, but don't see where I could adjust the selector actions zoom properties.

I've made a copy of my dashboard and tried editing the json to add the "pointZoomScale": 10, line however after saving and reopening the dashboard no change. When I tap my list, all other points still disappear leaving only the one, but my map does not zoom into that point at all (which can make it extremely difficult to find).

Where exactly does the pointZoomScale need to be added into the json? If it's in the correct location (I've tried it in the following 2 places), is there an configuration I'm missing in the dashboard?

Thanks!

Alicia

It looks like you're in the correct spot, but a zoom level of 10 would put your eyeball right up against a grasshopper's kneecap.

Try something like 1,500, and make sure you don't have a filter action that is filtering your other points (or filtering a list that has it's own filter action, etc). You should be able to change the point zoom scale in the dashboard map's settings once you change it in the JSON (in my experience).

I have the same issue as well. The zoom to polygons is not very good. Is there a setting that can be changed for polygons? Aaron Pulver‌

Is there a conversion of pointZoomScale values to the pre defined zoom levels on a map?

What version of Portal are you all using? I am using 10.7 right now, and over-writing the json for the pointZoomScale from 10,000 to 1,500 has no affect on my dashboard. I am using a list widget for a point layer with the Zoom set up.

I am trying to troubleshoot this question as well but with polygons. The answer states that the map should zoom into a polygon and that is not true. How do we change this for polygons? Thank you in advance!

Elizabeth Ayarbe, I was never able to get polygons to work. I made invisible points inside each polygon, then I used one point zoom level that was the best fit for viewing the polygons. It is a work around, but it gets the job done and it looks like it is zooming in on the polygons.

Thank you for your quick response. I'll try doing the same. I was also thinking of creating a negative buffer that falls within the polygon feature and use that as my feature to zoom to. I'll see which one works best. Thank you again!

Did anyone ever provide a solution to change the zoom to extent for polygons?

I'm working on a dashboard with different project areas that could end up having very different sizes and shapes. The polygon zoom doesn't zoom in close enough to see the details of the project, and the point zoom is not going to work for all the project areas since they're all different sizes.

It would be nice if when you set a zoom action in a dashboard there were zoom extent settings similar to those for Data Driven Pages/Map Series in ArcMap/Pro.

This is a great solution....why is it that when we are trying to do JSON code changes people always post screenshots of the code? WHY??? Just paste the text in here with formatting. Having to type out these long strings of code just leaves more room for error.
