Property Value

Type	Default	Description
String	"#666666"	The point color.

Remarks

The FirstLastColor property accepts the following formats:

• RGB and RGBA color codes: rgb(255, 0, 0), rgba(0, 230, 0, 0.3).

DxSparkline highlights the first and last series points. Use the FirstLastColor property to specify the color of such points.
