How to bind data to the Sparkline chart (SfSparkLineChart)?

There are two different ways to bind the data source to the SfSparklineChart widget. One is directly binding the data, for example list of y values to the data property of SfSparkLineChart widget, and another one is binding the custom data source using SfSparkLineChart.custom.

• Using the data property - Initialize the data source sparkChartData of required type, declared the type as double.
• Binding Custom data source - Here, you can define our custom type data source. By using the dataCount property, you can assign the number of data and then you can map x and y value of our data source using the xValueMapper and yValueMapper, respectively.
