The first scenario works because passing an array of strings to the values property is a convenience pattern when you're only working with one value. The second example is using incorrect syntax. You can't pass an array to values.value or values.value2. The values property takes an array of objects, like this... That way you can pair up values that go together in a    const renderer = { type: "unique-value", field: "test1", field2: "test2", uniqueValueGroups: [{ heading: "Heading 1", classes: [{ label: "Label 1", symbol: { type: "simple-marker", style: "circle", color: "#58ff60", outline: { color: "rgba(140,255,120,0.5)", width: 6 } }, values: [{ value: "testValue" }, { value: "testValue1", }, { value2: "testValve2" }] }, { label: "Label 2", symbol: { type: "simple-marker", style: "circle", color: "#58ff60", outline: { color: "rgba(140,255,120,0.5)", width: 6 } }, values: { value: "testValue3", value2: "testValve4" } }] }] }   Or if you want field1 and field2 values combined to represent one category, you specify the values for each within a single object.   values: [{ value: "testValu1", value2: "testValue2" }, { value: "testValue3", }, { value2: "testValve4" }] ...

1. I need more detail here. Specifically, what are the more complex cases? Is it just that you have more categories? 3. I think you misunderstood that line of documentation. Individual features are displayed. That line is specifying how those features get their symbol. If you specify a cluster renderer, all features (clusters and individual features) are styled using the cluster renderer. That is what is meant by "cluster renderer overrides the style of the features in the view". If you don't specify a cluster renderer, the cluster style is inferred from the layer renderer, which determines how individual features are styled. This isn't a change we're going to revert. The previous behavior is wrong even if that's what you were used to. Many people called support pointing this out and requesting this change. I suggest using the pie chart style in your scenario. If I see a lot of default symbols in clusters in a scenario like this, that tells me that pie chart is more appropriate anyway since there is no clear pattern of predominance. You also have options for how many categories to display in pie chart clusters...and individual features will display with the color of the category to which they belong as a solid color. Since the behavior was incorrect previously, I don't consider this a breaking change. If you notice strong visual differences in this scenario with clustering when upgrading the API version, it's exposing the problems we had in previous versions of the API, rather than the introduction of a bug in newer versions. ...

This is actually a result of a bug "fix" related to cluster visualizations with unique value renderer. Neither visual is great in my opinion. Without a cluster renderer, the cluster uses the symbol of the most common category (or uniqueValueInfo) contained within the cluster. Your dataset involves tie values. Prior to 4.25, in the case of a tie where the most common category was in a tie with another category, the rendering engine just picked one of the symbols and used it. This is problematic since it portrays predominance in one category when it doesn't actually exist. At 4.25, we updated this to match our predominance renderer for layers so tie values are represented with the default symbol. I don't think this is a perfect solution as the default symbol makes it look like the features don't belong to any of the categories. There are a couple of things you can do to change the visual. 1. Use a pie chart renderer for the cluster style. This will show the actual breakdown of categories within the cluster. This is great for scenarios where predominance can be misleading even when tie values are not involved. However, it can make it hard to read if a lot of categories are in play. In your scenario, where there are only 3 categories (a fourth being tie values), I think this is a fine option. 2. You can update the defaultSymbol on the layer style and indicate it represents "tie values" by setting a defaultLabel.  3. You can override the default cluster renderer with your own unique value renderer accounting for ties using a distinct symbol.    Hopefully that helps.   ... View more

Yes. You can do this with the smartMapping statistic functions. In this case you need summaryStatistics. You can also get a histogram and unique values with count if needed. You just need to be sure to set the forBinning parameter to true.     const stats = await summaryStatistics({ layer, view, field: "aggregateCount", forBinning: true });     Here's a codepen that demonstrates how to do it for the basic configuration sample you posted: https://codepen.io/kekenes/pen/bGmEvWj?editors=1000 Let me know if you run into issues. ...

I would try using the new uniqueValueGroups for this purpose. The way you declare which value belongs to which field is more explicit, so you're less likely to run into issues. Try this... // This example groups categories under three headings: // Commercial, Residential, and Other layer.renderer = { type: "unique-value", field: "farmType", field2: "livestockType", fieldDelimiter: ", ", uniqueValueGroups: [{ classes: [{ label: "Pig", symbol: { type: "picture-marker", url: "https://cdn-icons-png.flaticon.com/512/776/776450.png", width: "25px", height: "25px", outline: { color: [255, 255, 255], width: 1, }, }, values: { value: 1, value2: null, value3: null } }, { label: "Cow", symbol: { type: "picture-marker", url: "https://cdn-icons-png.flaticon.com/512/6165/6165370.png", width: "25px", height: "25px", outline: { color: [255, 255, 255], width: 1 } }, values: { value: 2, value2: 1, value3: null } }, { label: "Goat", symbol: { type: "picture-marker", url: "https://cdn-icons-png.flaticon.com/512/8686/8686214.png", width: "25px", height: "25px", outline: { color: [255, 255, 255], width: 1 } }, values: { value: 2, value2: 2, value3: null } }, { label: "Slaughterhouse", symbol: { type: "picture-marker", url: "https://cdn-icons-png.flaticon.com/512/1995/1995607.png", width: "25px", height: "25px", outline: { color: [255, 255, 255], width: 1 } }, values: { value: 3, value2: null, value3: null } }, { label: "Chicken", symbol: { type: "picture-marker", url: "https://cdn-icons-png.flaticon.com/512/1449/1449791.png", width: "25px", height: "25px", outline: { color: [255, 255, 255], width: 1 } }, values: { value: 4, value2: null, value3: null } }] }] };   ...

Hi @JulienHenchoz , for rendering inconsistencies between JS API versions, I suggest reaching out to Esri Support so they can verify the issue and log it into our system. For the most part, maps between 3x and 4x should look the same. There are some cases where you may see minor differences. These ones are probably worth a look on the support side. ... View more

@Bud Adding a page for working with vertices is a good idea. I'll add this to our list of todos for a documentation enhancement. Thanks for reaching out. ... View more

It must be intentional, since I've been unable to share links in replying to comments in the past. I'll pass along the info to the ArcGIS Blog folks to get a more official response. ... View more

No. This feature isn't available in ArcGIS. The equivalent functionality is browse features, which allows you to view the titles of all popups in a cluster, click to view the individual feature's popup and view it's actual location on the map.  You can also use alternate approaches to clustering if you want the "flare" behavior. Here's one available on GitHub: https://github.com/nickcam/FlareClusterLayer And an example: http://flareclusterlayer.azurewebsites.net/index_v4.html . The images below show the default behavior in the JS API. Note the symbol for the selected feature in the browse action is too small to really see. That is because it uses the symbol directly set on the layer's style. To see it better, just bump up the size of the symbol.   ... View more

Can you post a link to a codepen demonstrating the issue. It's hard to debug without seeing this config connected to real data. ... View more

That pattern isn't supported in 4.x. Rather than set a symbol for each graphic, you should set a renderer on the FeatureLayer. In this case you would set a SimpleRenderer with a PictureMarkerSymbol on the symbol property. Very similar to how you see it in this sample: https://developers.arcgis.com/javascript/latest/sample-code/layers-featurelayer-collection/  ... View more
