I would like to add a pie chart to a popup on a map (using the new map viewer). My data looks like this: Nitrogen and Phosphorus Source Apportionment by Land Use Type - Data (arcgis.com)
I have no experience of using Arcade and most examples i can find online make use of JavaScript, which i also don't know. I found an example somewhere that i used as a template (see below) , but this doesn't seem to work on it's own:
return {
type: "media",
// defines attribute values calculated in the expression
// values for all charts must be included here
attributes: {
field1: Number($feature.N_EXPORT_PC_SPRING_BARLEY),
field2: Number($feature.N_EXPORT_PC_OTHER),
field3: Number($feature.N_EXPORT_PC_GRASS),
field4: Number($feature.N_EXPORT_PC_MAIZE),
field5: Number($feature.N_EXPORT_PC_WINTER_BARLEY),
field6: Number($feature.N_EXPORT_PC_WINTER_WHEAT),
field7: Number($feature.N_EXPORT_PC_OILSEED_RAPE),
field8: Number($feature.N_EXPORT_PC_SOLAR),
field9: Number($feature.N_EXPORT_PC_SPRING_WHEAT),
field10: Number($feature.N_EXPORT_PC_FIELD_BEANS),
field11: Number($feature.N_EXPORT_PC_DISCONTINUOUS_URBAN),
field12: Number($feature.N_EXPORT_PC_DUMP_SITES),
field13: Number($feature.N_EXPORT_PC_INDUSTRIAL_OR_COMME),
field14: Number($feature.N_EXPORT_PC_CONSTRUCTION_SITES),
field15: Number($feature.N_EXPORT_PC_SPORT___LEISURE_FAC),
field16: Number($feature.N_EXPORT_PC_CONTINUOUS_URBAN_FA),
field17: Number($feature.N_EXPORT_PC_MINERAL_EXTRACTION_)
},
title: "Media content title",
mediaInfos: [
{
type: "piechart", // can also be "columnchart", "linechart", "piechart", "image"
title: "Chart title",
value: {
// the list of attribute values to include in the chart
fields: [ "field1", "field2", "field3", "field4", "field5", "field6", "field7", "field8", "field9", "field10", "field11", "field12", "field13", "field14", "field15", "field16", "field17" ]
}
}
// you can define more charts here
]
}
Can anyone tell me what else i need to add to make this work?
