Creating a chart through arcade expression in popups

Hi,

I am trying to add charts to my popups and was able to get the result from the image below:

but in my popup the chart just kept loading and refused to show up at all:

I'd appreciate it if anyone could shed some light on what I did wrong. Thanks.

Here is my Arcade expression:

var a = FeatureSetByName($datastore, 'Data', ['Bldg_Num', 'Room_Type_Description', 'ASF'])

var bn = $feature.BuildingNumber

var v = Filter(a, 'Bldg_Num=@bn')

var stats = GroupBy(v, 'Room_Type_Description', {name: 'Area', expression: 'ASF', statistic: 'SUM'})

var allSpcTP = OrderBy(stats, 'Area')

var Values = {}

var pieNames = []

for (var i in allSpcTP){

Values[i.Room_Type_Description]= Number(i.Area);

Push(pieNames, i.Room_Type_Description)

}

return {

type: "media",

attributes:Values,

mediaInfos:{

type: "barchart",

title: 'Room type sqare footage',

value: {

fields: pieNames

}

I think its that mediaInfos should be an array since you can have multiple charts:

return { type: "media", attributes:Values, mediaInfos:[{ type: "barchart", title: 'Room type sqare footage', value: { fields: pieNames } }] }

Thank you! It works.

You just saved me from insanity...
