matplotlib.pyplot.pcolormesh

 matplotlib.pyplot.pcolormesh(*args, alpha=None, norm=None, cmap=None, vmin=None, vmax=None, shading='flat', antialiased=False, data=None, **kwargs)      创建一个带有不规则矩形网格的伪彩色图

Parameters:	C : array_like A scalar 2-D array. The values will be color-mapped. X, Y : array_like, optional The coordinates of the quadrilateral corners. The quadrilateral for C[i,j] has corners at: (X[i+1, j], Y[i+1, j]) (X[i+1, j+1], Y[i+1, j+1]) +--------+ | C[i,j] | +--------+ (X[i, j], Y[i, j]) (X[i, j+1], Y[i, j+1]), Note that the column index corresponds to the x-coordinate, and the row index corresponds to y. For details, see the Notes section below. The dimensions of X and Y should be one greater than those of C. Alternatively, X, Y and C may have equal dimensions, in which case the last row and column of C will be ignored. If X and/or Y are 1-D arrays or column vectors they will be expanded as needed into the appropriate 2-D arrays, making a rectangular grid. cmap : str or Colormap, optional A Colormap instance or registered colormap name. The colormap maps the C values to colors. Defaults to rcParams["image.cmap"]. norm : Normalize, optional The Normalize instance scales the data values to the canonical colormap range [0, 1] for mapping to colors. By default, the data range is mapped to the colorbar range using linear scaling. Normalize实例将数据值缩放到用于映射到颜色的规范化colormap范围[0,1]。默认情况下，使用线性缩放将数据范围映射到colorbar范围。 vmin, vmax : scalar, optional, default: None The colorbar range. If None, suitable min/max values are automatically chosen by the Normalizeinstance (defaults to  the respective min/max values of C in case of the default linear scaling). edgecolors : {'none', None, 'face', color, color sequence}, optional 　　边缘颜色，默认None: 'none' or '': No edge. None: rcParams["patch.edgecolor"] will be used. Note that currentlyrcParams["patch.force_edgecolor"] has to be True for this to work. 'face': Use the adjacent face color. An mpl color or sequence of colors will set the edge color. The singular form edgecolor works as an alias. alpha : scalar, optional, default: None 　　透明度 shading : {'flat', 'gouraud'}, optional The fill style, Possible values: 　　填充式样 'flat': A solid color is used for each quad. The color of the quad (i, j), (i+1, j), (i, j+1), (i+1, j+1) is given by C[i,j]. 'gouraud': Each quad will be Gouraud shaded: The color of the corners (i', j') are given by C[i',j']. The color values of the area in between is interpolated from the corner values. When Gouraud shading is used, edgecolors is ignored. snap : bool, optional, default: False Whether to snap the mesh to pixel boundaries.
Returns:	mesh : matplotlib.collections.QuadMesh
