The Flutter 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.
Four different types of rendering such as natural, monotonic, cardinal, and clamped.
Rotate the spline chart to plot data in a vertical direction and view data from a different perspective.
Empty or null data points are elegantly handled in spline charts.
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.
Use multiple axes to plot different data sets that widely vary from one other.
