WebJan 23, 2024 · To plot a smooth curve, we first fit a spline curve to the curve and use the curve to find the y-values for x values separated by an infinitesimally small gap. We can get a smooth curve by plotting those points with a very infinitesimally small gap. We can use the following methods to create a smooth curve for this dataset : 1. WebLine smoothing (aka anti-aliasing) works by inserting semi-transparent pixels at the edges of the actual plot line, thereby giving an optical illusion of a smooth line without pixelization …
