The Flutter spline area chart is designed for visualizing quantitative data. It is an area chart type that plots a fitted curve through each data point in a series. It is used to represent time-dependent data and show trends in data at equal intervals.
Rotate the spline area chart to plot data in a vertical direction and view data from a different perspective.
The spline area chart handles empty or null data points elegantly.
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.
