Format y-axis numbers as thousands or millions

[mithunadhikari40]

First of all I want to thank you guys for this wonderful library. I am using this to display some bar chart and I am wondering if there is any possibility for showing numbers in y-axis in a formatted way. For example:
16432 => 16K
1,000,000 => 1.00M
1,234,567 => 1.23M.

Here is a snapshot of the code I am using.

<BarSeries<ReportDataModel, String>>[
      BarSeries<ReportDataModel, String>(
          enableTooltip: true,
          dataSource: targetList,
          xValueMapper: (ReportDataModel sales, _) => sales.objectName,
          yValueMapper: (ReportDataModel sales, _) => sales.value,
          name: AppLocalizations.of(context).Total_Sales),
      BarSeries<ReportDataModel, String>(
          enableTooltip: true,
          dataSource: quantityList,
          xValueMapper: (sales, _) => sales.objectName,
          yValueMapper: (sales, _) => sales.value,
          name: AppLocalizations.of(context).target),
    ]

Here in the yValueMapper is there any way to show sale.value as formatted string like 16K or 1.23M rather than the actual numbers like 16000 or 1230000

Thank you.

Hi @mithunadhikari40 ,

Thanks for your interest in Syncfusion charts. We have analyzed your scenario and we have created a simple sample in order to format the axis labels from showing numbers to compact representations using the numberFormat property available in the axis. Please refer the code snippet below.

SfCartesianChart(
            primaryYAxis: NumericAxis(
              numberFormat: NumberFormat.compact()
            ),
)

And, also for formatting the axis labels with two decimal digits in compact representation, please refer the code snippet below to achieve it.

SfCartesianChart(
            primaryYAxis: NumericAxis(
              numberFormat: NumberFormat.compactCurrency(
                symbol: '',
                decimalDigits: 2
            ),
)

The sample for reference can be found below.
