Call signatures:: tripcolor(triangulation, c, *, ...) tripcolor(x, y, c, *, [triangles=triangles], [mask=mask], ...) The triangular grid can be specified either by passing a `.Triangulation` object as the first parameter, or by passing the points *x*, *y* and optionally the *triangles* and a *mask*. See `.Triangulation` for an explanation of these parameters. It is possible to pass the triangles positionally, i.e. ``tripcolor(x, y, triangles, c, ...)``. However, this is discouraged. For more clarity, pass *triangles* via keyword argument. If neither of *triangulation* or *triangles* are given, the triangulation is calculated on the fly. In this case, it does not make sense to provide colors at the triangle faces via *c* or *facecolors* because there are multiple possible triangulations for a group of points and you don't know which triangles will be constructed. Parameters ---------- triangulation : `.Triangulation` An already created triangular grid. x, y, triangles, mask Parameters defining the triangular grid. See `.Triangulation`. This is mutually exclusive with specifying *triangulation*. c : array-like The color values, either for the points or for the triangles. Which one is automatically inferred from the length of *c*, i.e. does it match the number of points or the number of triangles. If there are the same number of points and triangles in the triangulation it is assumed that color values are defined at points; to force the use of color values at triangles use the keyword argument ``facecolors=c`` instead of just ``c``. This parameter is position-only. facecolors : array-like, optional Can be used alternatively to *c* to specify colors at the triangle faces. This parameter takes precedence over *c*. shading : {'flat', 'gouraud'}, default: 'flat' If 'flat' and the color values *c* are defined at points, the color values used for each triangle are from the mean c of the triangle's three points. If *shading* is 'gouraud' then color values must be defined at points. other_parameters All other parameters are the same as for `~.Axes.pcolor`. rgouraud)rNzIPositional parameter c has no effect when the keyword facecolors is givenz;The length of facecolors must match the number of triangleszjtripcolor() missing 1 required positional argument: 'c'; or 1 required keyword-only argument: 'facecolors'z3.6z!Additional positional parameters z\ are ignored; support for them is deprecated since %(since)s and will be removed %(removal)s)messagerzQThe length of c must match either the number of points or the number of triangles)g? linewidth linewidthsnone edgecolor edgecolors antialiased antialiasedsF)r zashading='gouraud' can only be used when the colors are specified at the points, not at the faces.)r arrayr r )axis) r check_in_listrget_from_args_and_kwargs warn_externallen triangles ValueError TypeErrorwarn_deprecatednpasarrayxpop setdefaultlowercheck_isinstancerrget_masked_trianglesstackymeanmaskr _scale_normgridminmaxupdate_datalimautoscale_viewadd_collection)axr r r r r rrargskwargstri point_colorscrrec collection maskedTrisvertscolorsminxmaxxminymaxycornerss :/usr/lib/python3/dist-packages/matplotlib/tri/tripcolor.py tripcolorrJ smh  *G<%>>OOCv     & ' z?c#--0 0,- -AB BY]  !B8,B C D JJtAw  q6SZ LJ Vs3==) )LJDE E Jf%zz+6| lJ/Jf%zz+6|   < 4B!'M!:~V# f(?bI  !*-222:F XX ! *FF#EDf)-DDrRs,:'6 #DtDQrK
