.. _sphx_glr_plot_types_unstructured: .. _unstructured_plots: Unstructured coordinates ------------------------- Sometimes we collect data ``z`` at coordinates ``(x,y)`` and want to visualize as a contour. Instead of gridding the data and then using `~.axes.Axes.contour`, we can use a triangulation algorithm and fill the triangles. .. raw:: html
