I have checked spline graph in excel-2013 chart. But MS-Excel does not provide spline chart support. Does anyone know a workaround solution to render spline chart without using add-on and algorithm to generate points?

Excel's XY Scatter chart with the "smoothed line" option ticked uses a spline, to be precise, of the many different types of splines, it uses a Bezier spline.
