Some remarks on a rational cubic spline for the visualization of monotonic data

Abstract A smooth rational cubic spline interpolation scheme, to preserve the shape of monotonic data, was developed by Sarfraz (Computers & Graphics 2000;24(4): 509–16). The paper (Computers & Graphics 2000;24(4): 509–16), after a further study, motivated to mention few remarks. This article is devoted towards the compilation of those remarks.
