WebCubic hermite splines are a better tool for the job. Lagrange interpolation will make a curve that passes through the data points, thus preserving C0 continuity, but hermite splines preserve the derivatives at the edges while also passing through the data points, thus preserving C1 continuity and looking much better.
WebLagrange interpolation simply interpolates with a cubic polynomial the two points below the region and the two points above the region. The function is continuous at each point, …
