No. If you want smoother contours you can either use a 2-D interpolation method to map your data to a finer grid and then use that for contouring, or you can use a spline algorithm to smooth the contour paths directly. There are more problems and pitfalls with the second method than with the first, so don't bother trying it. >> Maybe I missed it in the documentation, but it's not clear to me. >> Thanks in advance, >> > I think it's the same than this used in the imshow method.

Imshow uses any of several 2-D interpolation methods to map values given on one square grid onto another square grid. It does not create paths; it simply displays pixels. In contouring, linear interpolation is used to find the intersections between contour level lines and grid lines; the intersection points are connected by line segments; and the line segments are assembled into complete contour paths, which are then drawn (contour) or filled (contourf).
