Creating an Arcade pop-up bar chart in Map Viewer

Hi, I'm wondering if any Arcade experts can help me please? Using the below expression, I am able to list out the average rainfall in mm prior to a defect report date.

var weather = FeatureSetByName($map, "Weather Stations", ["*"], false) var station = $feature.Closest_WeatherStation var defectdate = $feature.Reported_Date___Time var startDate = DateAdd(defectdate, -30, "days"); var endDate = DateAdd(defectdate, -1, "days"); var query = "Station = @station AND Date_Field >= @startDate AND Date_Field <= @endDate " var filtered_weather = Filter(weather, query) var return_lines = [ Count(filtered_weather) + " days forecast", ] for(var d in filtered_weather) { Push(return_lines, "Total Rainfall " + d.Daily_Total_Rainfall__0900_0900 + " mm") } return Concatenate(return_lines, Textformatting.NewLine)

However, rather than a list, I would like to display my results in a bar chart, displaying the date on the x axis and the total rainfall in mm on the y axis. Is anyone able to help with this please?

I have tried this following the page Part 2: Introducing Arcade Pop-up Content Elements (esri.com):

var chartValues = {} var chartNames = [] for (var f in return_lines) { chartValues[f.Date_Field] = f.Daily_Total_Rainfall__0900_0900 Push(chartNames, f.Date_Field) } return { type: 'media', title : 'Rainfall by Date', description : 'Chart showing total rainfall 30 days prior to defect report date', attributes : chartValues, // replace this dictionary with your own key-value pairs, mediaInfos: [{ type : 'columnchart', //linechart | barchart | piechart | columnchart //title : '', //caption : '', altText : 'bar chart showing crime counts by category', //altText will be read by screen readers value : { fields: chartNames, // choose what attributes to use in the chart //normalizeField : '', // the name of the attribute to normalize by or value } }] }

But i'm only getting this output
