| 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:
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.
