## SparklineGroup class

<see cref="Sparkline"/> is organized into a sparkline group.A SparklineGroup contains a variable number of sparkline items.A sparkline group specifies the type, display settings and axis settings for the sparklines.

```go

type SparklineGroup struct  {
	ptr unsafe.Pointer
}
