Symbology Quantities to show count

JakeKrall — Mon, 12 Jul 2010 21:02:24 GMT

When symbolizing features using Quantities (Symbology tab), I would like to see a "COUNT" field next to RANGE and LABEL to show how many features fall into each range. And show this "count" in the legend in the TOC and map layout legend with a toggle to show/not show.

Also, if symbology values change, such as date values that change daily, the symbology would auto-update w/out having to go into the Layer Properties>Symbology dialog, click the Value field each time to update the layer.

You might try this.

Add Feature Contents to a Legen: http://arcscripts.esri.com/details.asp?dbid=15069. It adds feature counts to each class' description in both class-breaks and unique-value renderers in ArcMap. Simply turn on the visibility of class descriptions in the legend to view these counts.

I haven't tried it out, so I don't know if it will work for Quanties, but it might be worth a shot.

I think this should be a core function. No matter how you symbolize, you should be able to see a count for each symbol, and if you can do that, then you should be able to toggle those counts on and off for the TOC/Legend.

Just to add to sabrown73's comment, the macro linked to below does work as advertised and is really useful. Would definitely be a good feature to include as standard.

How does the script in the follow link work in ArcGIS 10?:
Why this feature is not included in current versions?

This feature seems to exist in #arcdesktop 10.5‌, but not #arcpro 2.4‌

Michelle, are you referring to the count being shown in a legend or the Table of Contents of the map? Showing it in the legend is possible in both ArcMap and Pro. Showing it in the TOC/Contents Pane is not possible in either, and as far as I can tell would be the focus of this idea.

Right. Currently, the count of values of each class can be displayed in the legend. It would be great if the count of values (where applicable) of each class and their percent (%) can be displayed next to each class in the content pane without the need to calculate them

Hi Kory,

One of the capabilities that I keep going back to ArcMap for is seeing the counts in the symbology pane as seen in the picture below. I often use this as a guide to determine which classes I may want to merge or may not be represented in the dataset.

Is this available in ArcPro and I'm just unaware of where to look?

Thanks!

Michelle

Hi Michelle Totman‌

Did you see the Show Count option?

I think that should work for what you're describing.

Hope that helps!

Original poster should clarify that this is for the Table of Contents in a map, and not the layout (which I think we all know is possible). This could be done by the user right-clicking the label column header in the symbology window and selecting "Add count." The count column is already there. Why not use it?

I seem to remember doing an ArcObjects exercise back in the early oughts on doing this programmatically in VBA. The corresponding source for ArcPy has no mention of the class for the display of the symbology: https://pro.arcgis.com/en/pro-app/latest/arcpy/mapping/symbology-class.htm

'Show Count' in graduated colors, graduated symbols symbology

wayfaringrob — Tue, 07 Jun 2022 22:52:33 GMT

Unique values symbology has this lovely little option for showing the count of items in each particular class:

It would be quite useful to have the same tool added to graduated colors and graduated circles symbology.

The histogram is sometimes okay for a quick eyeballing, but it would really be ideal to just see raw counts without a workaround.

Hello every one
How can I find this option in ArcGIS pro ? I want show the counts from Symbology classes could you show that for me please ?

Re: Symbology Quantities to show count

wayfaringrob — Wed, 08 Jun 2022 15:27:48 GMT

Hey @ShabanUKM - in Pro, the count feature is currently only available in Unique Values symbology. It looks like you may be using Graduated Colors.

Yes, I agree this enhancement would good! As a college professor teaching cartography and classification methods, this would be very helpful in understanding the differences -- especially when choosing Quantiles as the method.

Side Note: I see several other comments in this thread indicating there is a "Show Count" option; but that is ONLY for 'qualitative/unique value/text field' maps. ...What we're taking about here is needing that option for 'quantitative/numerical field' maps!

Re: Symbology Quantities to show count - Status changed to: Implemented

AmeliaBradshaw — Fri, 10 Mar 2023 22:21:08 GMT

This Idea has been implemented in ArcGIS Pro 3.1. Please see the What's New documentation for more new features in Pro 3.1.

The Ideas in ArcGIS Pro 3.1 blog will be wrapped up soon, highlighting all Ideas implemented in this release, including this one. Once complete, I will add the link to this comment.

This functionality is implemented partially.

Customers urgently need an option to see feature counts under TOC, too:

At the moment this is not possible.
