Overview
The ASP.NET Core Spline Area Chart is like an area chart except that the data points are connected by smooth lines. It supports features like zooming, panning, animation, and dynamic updates.
Multi series
Multi area series are useful to compare two or more cumulative values over a period.
Marker
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..
Multiple axes
Use multiple axes to plot different data sets that vary widely from each other.
Zoom and pan
Enable zooming and panning when dealing with large amounts of data to focus on particular ranges.
Empty/null data point
Handle missing data elegantly with empty points support.
Vertical chart
The ASP.NET Core Spline Area Chart can be transposed vertically to view the data from a different perspective.
Customization
Customize the color and border of the ASP.NET Core Spline Area Chart using built-in APIs.
