ASP.NET Core Spline Range Area Chart is used to display continuous data points as a set of splines that vary between high and low values over intervals of time and across different categories.


Mark data points with built-in shapes: circles, rectangles, ellipses, vertical lines, horizontal lines, diamonds, triangles, pentagons, crosses, and pluses. In addition to these shapes, use images to make the points 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 a given angle.

Empty/null data point

Handle missing data elegantly with empty points support.

Vertical chart

ASP.NET Core Spline Range Area Chart can be transposed vertically to view the data from a different perspective.


Customize the color and border of ASP.NET Core Spline Range Area Chart using built-in APIs.

Zoom and pan

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