A Range Spline Area series fills the smoothly curved region between high and low values, combining the visual clarity of spline interpolation with range-band representation for envelope and volatility analysis.
This sample maps CSCO high and low prices to a range spline area in the main 50%-height panel, with supporting spline area plots for MSFT and CSCO close values below. A custom HTML tooltip formatter displays high/low values consistently, and a stock scroller, range picker, and range selector provide time-window navigation across all three plots.
See the AnyStock Series documentation for all configuration options.
