The Angular range area chart is used to show variation in data values for a given time. It is like the area series, except that the area between the high and low ranges is filled.
Mark data points with built-in shapes: circles, rectangles, ellipses, vertical lines, horizontal lines, diamonds, triangles, and pentagons. In addition to these shapes, use images to make the points more attractive.
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.
Handle missing data elegantly with empty points support.
The Angular range area chart can be transposed vertically to view the data from a different perspective.
Customize the color and border of the range area chart using built-in APIs.
Enable zooming and panning when dealing with large amounts of data to focus on particular ranges.
Easily get started with Angular Range Area using a few simple lines of JS code, as demonstrated below. Also explore our Angular Range Area Chart Example that shows you how to render and configure the range area chart component.
