Change pie chart slice colors?

I am creating a hub for aquatic barrier data, and I would like my pie chart to be color coded from green to red. Is it possible to change the pie slice colors within the chart?

Thank you!

Hi Kathleen,

Yes it is possible.

Once you selected the chart on the page, change the "Chart Type" to JSON.
Near the end of the JSON code, you can add the styles tag and then the colors option with the various colours in hex code.
In the example below, you will see the addition I made starting at line 31 to line 41.
Don't forget to add a comma like I did at line 30 or you'll will get an error.

{ "type": "pie", "datasets": [ { "url": "https://services.arcgis.com/uDTUpUPbk8X8mXwl/arcgis/rest/services/Public_Schools_in_Onondaga_County/FeatureServer/0", "query": { "orderByFields": "Number_of_SUM DESC", "groupByFieldsForStatistics": "Type", "outStatistics": [ { "statisticType": "sum", "onStatisticField": "Number_of", "outStatisticFieldName": "Number_of_SUM" } ] } } ], "series": [ { "category": { "field": "Type", "label": "Type" }, "value": { "field": "Number_of_SUM", "label": "Number of Students" } } ], /* Add in this style piece. You will want as many hex colours as items in your pie chart. It colours the slices in the same order as they're listed */ "style": { "colors": [ "#f6eff7", "#dbc9e1", "#67a9cf", "#02818a", "#1c9099", "#016c59" ] } }
