Can I use two layers on thematic widget?

Hi Fabiano,

Currently the compiled configuration supports just one layer at a time. You could customize the source code to meet your needs if that is an option for you.

I have issues making it work by only modifying the widget parameters in Flex Viewer! Could you please tell me if you see something in the configuration statement? Thanks!

Hi Sofie,

The thematic widget uses the server's (dynamic) thematic rendering capabilities which was introduced in version ArcGIS 10.1. If you upgrade your server software to version 10.1 and compile the widget for ArcGIS API/Viewer 3.0, then it will work. See:
http://resources.arcgis.com/en/help/flex-api/apiref/index.html?com/esri/ags/tasks/GenerateRendererTask.html&com/esri/ags/tasks/class-list.html

Double check your services directory for the layer id and layer name, see the graphic below. Make sure your layer name and id match in your services directory.

[ATTACH=CONFIG]24510[/ATTACH]

The classificationFieldTypes are the "physical" names of the fields in your sda_mus layer, and the classificationFieldTypeDescs are the aliases that will be presented to the user in the User Interface.

<classificationFieldTypeDescs>Field Alias 1,Field Alias 2</classificationFieldTypeDescs>
<classificationFieldTypes>Field1,Field2</classificationFieldTypes>

Make sure your server is running ArcGIS 10.1 software or later, also make sure you have enabled the "dynamic capability" of the service in the ArcGIS Server Manager. The service will report "supportsDynamicLayers" true. See: http://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer?f=pjson. See number 5 in the list: http://resources.arcgis.com/en/help/main/10.1/index.html#/Enabling_dynamic_layers_on_a_map_service_in_Manager/015400000570000000/

How practical/possible is it to make this widget dynamic. So I can selected from all of my dynamic layers instead of having to hardwire only one layer into the code?

Hi Joe,

It is possible and practical, just not implemented yet. You can always implement it yourself, but I've added a GitHub issue to address this enhancement request also. I just didn't implement this functionality initially.

Re: thematic-widget-flex

JohnParker — Wed, 25 Sep 2013 17:53:26 GMT

In working with the widget if I have it open at the start, I have to close the widget and reopen the widget before it will create a thematic map based on one of the attributes. If the widget is not open at the beginning of the application, I have to open it, close it, and open it again before it will recognize the attributes and display the symbology.

Here is my code.

Re: thematic-widget-flex

LindseyHays — Mon, 30 Sep 2013 12:16:29 GMT

Hi Lloyd,

I'm experiencing a issue similiar to the one described by jparke1. My client and I created a flexviewer which uses the widget. The widget is set to open at start. The widget opens but the layer that is configured with it does not load in automatically. If I go to the "More" button in the upper right hand corner and turn the Thematic layer on and off the data loads in just fine and I am able to use the widget and switch between catagories without a problem.

I recreated the issue on my client's machine (different ArcGIS Server, different set up, different REST service). The issue is also consistent across the major browsers (I get the same thing in IE, Firefox and Chrome) so its not an IE thing.

Interestingly enough I don't see this behavior with the sample service that comes with the code. A viewer created with the sample service http://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer loads the states in automatically at start without any issues.

I have to admit I am new to dynamic services and this is my first experience working with them. Is there some service parameter I need to turn on to get this thing to load automatically? Any help you could provide will be much appreciated.

Thanks,

Lindsey

Version 3.5 has been released which fixes the issues previously posted and also adds an enhancement to support multiple layers within the same widget.

Hi Francisco,

Can you provide more useful information? It was working, now it isn't? What version of ArcGIS Server are you using? Are you using versions 3.5 of the Viewer and widget?

Do you know how to use a tool like Charles Web Debugging proxy, Fiddler for Internet Explorer, Firebug for Firefox, or the Chrome Developer Tools?

I've attached a text file that represents the request/response similar to what you should be seeing when using the tools mentioned above.

Hope this helps,

Hi Lloyd,
I'm having trouble with the widget not using the colors I entered for the High and Low range values. It seems to default back to two of the five colors from the config file. (charcoal and yellow used in the background and title text).

I'm on ArcGIS Server 10.1, ArcGIS 10.1, Flex Viewer 3.5 and Thematic Widget 3.5.

I had gotten it working in 3.4 but then my coworker and I wanted to be on the same version so I upgraded my Viewer and Thematic and now I can't get it working again.

I just noticed that the color ramp entries have moved to within the <layer> tag. I tried editing the xml so the census data would render with my colors but that didn't seem to work.

ThematicWidget_1.xml is below and can get my layer service file or the config.xml if you need it.

This can be done pretty easily in the source code.
Are you using Flash Builder or only editing the .xml files or using the Flex Application Builder?

Hi Skip,

I wanted to implement this when I was writing the samples and widget. Unfortunately if the server is performing the labeling, there aren't many options other than what is listed with the labelExpression. See the REST API link below.
ArcGIS REST API - label

You can see more advanced samples below:
LabelOptions Wizard
Dynamic labeling
Dynamic labeling - advanced

Here is the Flex doc:
Flex API doc - LabelClass
Flex API doc - LabelOptions

Can you please submit a support incident for this? This will create a internal tracking number for this issue which will be reviewed by the server team. The more customers that request this functionality will raise its priority to implement. Can you also create a suggestion on the ideas site?

Thank you,

I'm currently just editing in either the Application Builder or directly in the xml for the widget.
