Barchart removes duplicates

Question

So I have a bar chart and the data I am passing in is the first letter of each month along with some data so something like this:

List getChartData() {
  final List chartData = [
    Data('J', 12.0),
    Data('F', 15.6),
    Data('M', 17.5),
    Data('A', 14.7),
    Data('M', 12.4),
    Data('J', 15.9),
    Data('J', 12.3),
    Data('A', 14.5),
    Data('S', 12.8),
    Data('O', 13.4),
    Data('N', 13.2),
    Data('D', 11.9),
  ];
  return chartData;
}

But when I pass the data into the column series, it removes duplicates so I will only see 1 J on the bar chart when I should be seeing 3 (Jan, July, June).

How can I have duplicates in this barchart (all the months)?

Thanks, Please let me know if I am unclear on anything.

Hi Alvin,Greetings from Syncfusion. We would link to let you know that the
bar series with the same x value did not get removed, it is just appended one
on another. We suggest you use the arrangeByIndex property in the category axis it will help you
to render a bar chart based on the index. We have attached the code snippet
below to achieve your requirement.Code snippet:

SfCartesianChart(
    primaryXAxis: CategoryAxis(
      arrangeByIndex: true,
    ),
    // Other required properties
  )
