How can I change cluster colors dynamically based on the max count of an attribute ?

[TheUncharted]

Hi

I have some posts with an attribute category
I would like my cluster point to have the color of the category which has the most counts like this picture

Or if the max is not possible how can I display a custom marker like this example where the count are displayed
I found this picture on mapbox github issue

@TheUncharted you should be able to extract the max withclusterProperties. Then you can use set the color based on that property.

The second one is not really possible. You might try using iconImage with an expression generated from like: '23-30-56-90' which would mean 23 in first, 30 in second etc category. Then you could use the onImageMissing to generate the proper image for that name.

i tried something like that

clusterProperties={{
  category1: [
    ["+", ["accumulated"], ["case", ["==", ["get", "category"], "category1"], 1, 0]],
  ],
  category2: [
    ["+", ["accumulated"], ["case", ["==", ["get", "category"], "category2"], 1, 0]],
  ],
  category3: [
    ["+", ["accumulated"], ["case", ["==", ["get", "category"], "category3"], 1, 0]],
  ],
  MaxCategory: [
    ["max", ["get", "category1"], ["get", "category2"], ["get", "category3"]],
  ],
}}

and got this error if I add the max
I m not sure of the syntax
