Clustering in viewer 2.4

BjornSvensson — Sun, 12 Dec 2021 00:35:32 GMT

It hasn't made it in to the <layer> tag documentation yet, but there is a sample called "Clustering" listed on the "Samples" page.

Here are some examples of how to take advantage of the new <clustering> functionality in flex viewer 2.4.

Basic example:

<layer label="Simple, same-sized circles (default color green)"
           type="feature"
           url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/SanFrancisco/311Incidents/MapServer/0"
           popupconfig="popups/PopUp_311.xml"
           visible="true">
        <clustering>
            <clustersymbol type="simple"/>
        </clustering>
</layer>

The example from the online sample:

<layer label="San Franscisco 311" type="feature" url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/SanFrancisco/311Incidents/MapServer/0" popupconfig="popups/PopUp_311.xml" visible="true">
    <clustering mingraphiccount="2" sizeinpixels="80">
        <clustersymbol type="simple" alpha="1" alphas="0.7,0.8,1" bordercolor="0xFFFFFF" color="0xFF4242" colors="0xFF837E,0xFF4242,0xFF4242" flaremaxcount="10" size="90" sizes="30,60,90" textcolor="0x000000" textsize="14" weights="10,100,200"/>
    </clustering>
</layer>

    </clustering>

Trying to patiently wait for the updated documentation. But, can you give a brief description of what each of these settings is doing? Also, are there any other configuration options available for the clustering?

Thanks for a great new feature!!

I have three questions to clustering in flexviewer 2.4

1. When I zoom to max zoom level I still have some features clustered. Which parameter will I have to set to ensure that features will be displayed as single points when zoomed in?

2. Does flare working with clustering for flexviewer 2.4?

3. Does <linkfield> to images work for Popup window for clustered layer? When I mouse click on single points in the clustered layer for popups I only get the url displayed not the image.

Hi Ivan, I'm also working through this and have been able to figure out some of the properties.

1. Increasing the property minigraphcount (try 5 or more) should reveal those final few points when zoomed in.

2. Set clustersymbol type="flare" (this works, but is not currently supported because it has not yet been fully implemented)

3. You need to configure a custom popup.xml for the feature layer. Check the <medias> tag in the viewer documentation.

Hope this helps!

Thanks Evan for your help. This brought me a step further. I simply had not set clustersymbol type correct to "flare" and had not configured <media> correct for imagesource. Now it works.

Still I face the problem that some points are still clustered a maximum zoom level and thus may not be displayed by popup window. Are popup not working for the flared points.

In addition to this I don't succeed getting popups to work for dynamic layers. As I understand the documentation for Flexviewer 2.4 the new popups should work for tiled, dynamic and feature layers???

Hi,

I found the solution for popups with dynamic layers using sublayers. The new popups are just amazing. Sometime reading carefully the ArcGIS viewer for Flex documentation is really a very good place to start... 🙂

I can't get a popup to work on flared points either, is there something i am doing wrong?

<layer label="Test Clustering" type="feature" visible="true"
     popupconfig="popups/PopUp_SR_Ultrasoon.xml"
     url="http://gistest.railinfra.local/ArcGIS/rest/services/US_Data/MapServer/0">
     <clustering mingraphiccount="2" sizeinpixels="80">
        <clustersymbol type="flare" alpha="1" alphas="0.7,0.8,1" bordercolor="0x000000" color="0xFF4242" colors="0xFF837E,0xFF4242,0xFF4242" flaremaxcount="10" size="90" sizes="30,60,90" textcolor="0x000000" textsize="14" weights="10,100,200" /> 
       </clustering>
     </layer>

Thanks in advance.

No, you're not. This isn't supported in the current release, but is something we are looking at for version 2.5.

Ah, so I can stop trying now, haha. Thanks for the info!

does the clustering not work for "dynamic" layers? I have been able to make the sample data work in my viewer, but when I try to apply it to some of my real data it does nothing. The only major difference between the 2 that I've been able to see is the "type" in the sample data is "feature" and in MY data is "dynamic". Any help with this would be great.

Thanks

Correct - see http://help.arcgis.com/en/webapps/flexviewer/help/index.html#/The_Layer_tag/01m30000000p000000/

Clustering only works with layers of type "feature" (which can come from any one layer in either a MapService or a FeatureService). This is because feature layers refer to only one single layer, and the features are actually client-side. For the dynamic layers, those are map services of usually many (sub)layers and the map image is created on the server.

Bjorn,

Thanks for the response. Do you know if clustering dynamic layers will be avalible in future versions?

Thanks again

If you mean layers="dynamic", then no, because that image is created on the server by ArcGIS Server (as opposed to client-side in your browser).

If you mean a dynamic layer in more generic terms (as in "not tiled"), then it already is supported by adding a layer="feature" that points to one of the layers within that map service.

Has anyone had success with getting popup info support on the flare? I've tried, but I can't get it to work, and really that's the main selling point of the flare.

Jeff,

Popups on flares are not yet supported.

"flare" is not a supported cluster option at this time (version 2.4). See my previous reply on August 26 - and the updated clustering section in the documentation - http://help.arcgis.com/en/webapps/flexviewer/help/index.html#/The_Layer_tag/01m30000000p000000/

Flex viewer 2.5 just leased, is flare popup supported in the flex viewer 2.5? I am trying but flare pupup or map tip are not working so far.

AdamConner — Fri, 09 Dec 2011 17:54:14 GMT

I just upgraded to 2.5 and it does now show the proper icon on the flare graphics, but the click event to show the popup does not work unless there is an additional config option which must be enabled.

Re: Clustering in viewer 2.4

Hwa_SaupLee — Wed, 14 Dec 2011 14:03:16 GMT

So what would be the additional config to make the flare info popup?

Hi Adam,
We could sure use the additional config option which must be enabled. I have the cluster option working in FlexViewer 2.4. The flare spins up, but no popups work. No icons of the different categories work either. (But I didn't code anything other than a standard popup.xml.)
Thanks,
Janie
