[Arcade] Integrate array variable with a chart

[JasonBOCQUET]

Hi guys,

 have a list of society and establishment. Each society have only one headquarter and all of his other implantation are called establishment.

I represent on ArcGIS a map to see all of the establishment of many societies.

And i write a code to allow my users when clicking on a point to see all of the other establishment on the pop-up box who opened by clicking on the point.

next in my code i retrieve the year of creation of each establishment and (if exist) the year of closing of the establishment who are closed.

Finally i want to use quickchart.io to made a GANTT chart like to see all of the opening and closing year of each establishment linked to the establishment that the user clicked on.

But i've a problem, if the establishment is alone (because the society have not another establishment in the world) the chart works : 

but if I have 2 or more establishment, the chart do not work : 

Here is my code : 

var date_crea = $feature.ets_date_creation

var date_ferm = $feature.date_fin_ets_def



var fs = FeatureSetByName($map, "Ancienneté d'implantation siège", ['ets_date_creation', 'ets_siren'], false)
var ls = FeatureSetByName($map, "Ancienneté d'implantation siège", ['date_fin_ets_def', 'ets_siren'], false)
var filt_fs = Filter(fs, `ets_siren = '${$feature['ets_siren']}'`)
var filt_ls = Filter(ls, `ets_siren = '${$feature['ets_siren']}'`)

var match_arr = []
for (var f in filt_fs) {
  var match_arr_change = Left(f['ets_date_creation'],4)
  var date_crea_int = Number(match_arr_change)
  Push(match_arr, date_crea_int)
}

var match_larr = []
for (var f in filt_ls) {
  var match_larr_change = Left(f['date_fin_ets_def'],4)
  var date_fin_int = Number(match_larr_change)

  if (date_fin_int==0){
    date_fin_int=2024
  }
  Push(match_larr, date_fin_int)
  }


var HTML = ""
HTML += "<p style='text-align: center; line-height: 0.1;'><strong><span style='font-size: 30px; font-family: Calibri, sans-serif; color: rgb(1, 42, 132);'>"+"Date d'ouverture"+Concatenate(match_arr, "<br>")+"Date fermeture"+Concatenate(match_larr, "<br>")+"</span></strong></p>"



var param_charts = {
  type: 'horizontalBar',
  
  data: {
    labels: match_arr,
    datasets: [{
      data: 
        [[match_arr, match_larr]],
    },]
  },
  options: {
    legend: {
      display: false
    },
    annotation: {
      annotations: [{
        type: 'line',
        mode: 'vertical',
        scaleID: 'x-axis-0',
        value: 2030,
        borderColor: 'red',
        borderWidth: 1,
        label: {
          enabled: true,
          content: 'Deadline',
          position: 'top'
        }
      }]
    },
    scales: {
      xAxes: [{
        position: 'top',
        ticks: {
          min: 1900,
          max: 2030,
        }
      }],
    },
  },
}
var param_url = URLEncode(Text(param_charts)) 
var chart_url="https://quickchart.io/chart" + "?width=600&height=600&v=2&c=" + param_url
HTML += `<img src='${chart_url}' /></div>`

return { 
	type : 'text', 
	text : HTML
}

If anyone has a solution to help me please ! have a nice day
