Overview

The Xamarin.Forms spline chart resembles a line chart, but the difference between them is that instead of connecting the data points with straight lines, the data points are connected by smooth Bezier curves.

Beautiful Xamarin.Forms Spline Charts


Key features

Xamarin.Forms chart shows the different spline types

Spline type

Four different types of rendering such as natural, monotonic, cardinal, and clamped.

Shows the Xamarin.Forms vertical spline chart

Vertical rendering

Rotate the spline chart to plot data in a vertical direction and view data from a different perspective.

The Xamarin.Forms spline chart shows the empty or null point support

Empty points

Empty or null data points are elegantly handled in spline charts.

Xamarin.Forms chart shows the marker support in spline chart

Marker

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.

Xamarin.Forms chart shows the multiple axis support

Multiple axes

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