I know that one can get smooth point connections with option smooth
to \addplot
that takes the previous and the next point into account, but this still connects all the points.
How can I draw a smooth curve through the points using pgfplots
that are not necessarily connected? I'm not fully sure if this is correct, but I think I'm looking for "bezier curves" (correct me if wrong). To be clear: I do not want curve-fitting like one can do with gnuplot
, just some "sloppy-smooth" connecting of points.
