Hi,

It seems that Grouped & Stacked bar Apexcharts doesn't work for me. I've created a chart with same properties as this link.

On my designer it shows me that :

How can I resolve it ?

Thanks

My options property :

{
  "plotOptions": {
    "bar": {
      "horizontal": true
    }
  },
  "dataLabels": {},
  "xaxis": {
    "categories": [
      "Online advertising",
      "Sales Training",
      "Print advertising",
      "Catalogs",
      "Meetings"
    ],
    "labels": {}
  },
  "legend": {
    "horizontalAlign": "left",
    "position": "top"
  },
  "fill": {
    "opacity": 1
  },
  "stroke": {
    "colors": [
      "#fff"
    ],
    " width": 1
  },
  "chart": {
    "stacked": true,
    "type": "bar",
