Angular spline area chart are much like area chart expect that the data points are connected through a smooth line. Supports feature like zooming, panning, animation, and dynamic updates.

Multi series

Multi area series are useful to compare two or more cumulative values over a period.


Marks data points with built-in shapes such as circles, rectangles, ellipses, vertical lines, horizontal lines, diamonds, triangles, and pentagons. In addition to these shapes, use images to make the point more attractive.

Data label

Data labels display information about data points. Add a template to display data labels with HTML elements such as images, DIV, and spans for more informative data labels. You can rotate a data label by its given angle.

Multiple axes

Use multiple axes to plot different data sets that widely vary from one other.

Zoom and pan

Enable zooming and panning support when dealing with large amount of data to visualize the data point in any region.

Empty/null data point

Handle the missed data elegantly with empty points support.

Vertical chart

The spline area chart can be transposed vertically to view the data in a different perspective.


Customize the color and border of the spline area chart using built-in APIs.
