Select Cubic Spline or B-Spline.
-These are mathematical models that influence the display of the curves. The cubic spline line passes through all points, while the B-spline line connects the first and last point and passes by the intermediate points.
+These are mathematical models that influence the display of the curves. The curves are created by joining together segments of polynomials.
Optionally set the resolution. A higher value leads to a smoother line.
-For B-spline lines optionally set the data points order.
+For B-spline lines optionally set the degree of the polynomials.
