SplineAreaSeries<T, D> class

Renders the spline series.

To render a spline area chart, create an instance of SplineAreaSeries, and add it to the series collection property of SfCartesianChart. Properties such as color, opacity, width are used to customize the appearance of spline area chart.

Properties

animationDelay → double?
Delay duration of the series animation.It takes a millisecond value as input. By default, the series will get animated for the specified duration. If animationDelay is specified, then the series will begin to animate after the specified duration.
finalinherited
animationDuration → double
Duration of the series animation. It takes millisecond value as input.
finalinherited
borderColor → Color
Border color of the series.
finalinherited
borderDrawMode → BorderDrawMode
