Get the field "value" from mediaInfos to work in popup ArcGIS API JS

[julienrobitaille]

Hello,

I am trying to use the LineChartMediaInfo element in order to plot a simple array of points in the popup content. 

However, I dont really know how to make it work. Can the fields of the values contain arrays? 

Here is part of my code with a test array "array1" containing 4 numbers. 

            var pointGraphic = new Graphic({

                geometry: point,

                symbol: simpleMarkerSymbol,

                popupTemplate: popupTemplate,

                attributes: {

                    array1: [1, 2, 3, 4],

                    longitude: metadata["longitude"],

                    latitude: metadata["latitude"]

                }

            });

            var popupTemplate = {

                title: metadata["officialName"],

                content: [

                {

                    // Pass in the fields to display

                    type: "media",

                    mediaInfos: [{

                        title: "<b>Prédiction</b>",

                        type: "line-chart",

                        value: {

                            fields: ["array1"],

                            normalizeField: null

                        }

                    } ]

                }]

            };

I cant figure out from the doc (LineChartMediaInfo | ArcGIS API for JavaScript 4.17 )why it give me something like that:

Thanks a lot for your help!
