The triangulation to plot can be specified in one of two ways; either:: triplot(triangulation, ...) where triangulation is a `.Triangulation` object, or :: triplot(x, y, ...) triplot(x, y, triangles, ...) triplot(x, y, triangles=triangles, ...) triplot(x, y, mask=mask, ...) triplot(x, y, triangles, mask=mask, ...) in which case a Triangulation object will be created. See `.Triangulation` for a explanation of these possibilities. The remaining args and kwargs are the same as for `~.Axes.plot`. Returns ------- lines : `~matplotlib.lines.Line2D` The drawn triangles edges. markers : `~matplotlib.lines.Line2D` The drawn marker nodes. rN) linestylemarkercolorrNonezorder)rr)Nrr )Zaxisr)Zmatplotlib.axesrZget_from_args_and_kwargsxyedgesZaxesZ_baseZ_process_plot_formatcopyzipgetnpinsertnanZplotZravel)ZaxargskwargsZ matplotlibZtrir r rZfmtrrrkwkeyvalZkw_linesZ tri_lines_xZ tri_lines_yZ tri_linesZ kw_markersZ tri_markersr8/usr/lib/python3/dist-packages/matplotlib/tri/triplot.pytriplotsJ  r)ZnumpyrZmatplotlib.tri.triangulationrrrrrrs
