Colormaps added with register_cmap() take precedence over built-in colormaps. If name is a matplotlib.colors.Colormap instance, it will be returned. If lut is not None it must be an integer giving the number of entries desired in the lookup table, and name must be a standard mpl color...

In this example, we create a discrete color map with 5 bins using the ‘viridis’ color scheme. This approach is useful when you want to categorize your data into distinct levels represented by different colors. Alpha Blending Alpha blending allows you to control the transparency of colors in ...
https://matplotlib.org/stable/tutorials/colors/colormaps.html Choosing Colormaps in Matplotlib Matplotlib has a number of built-in colormaps accessible viamatplotlib.cm.get_cmap. There are also external libraries that have many extra colormaps, which can be viewed in theThird-party colormapssection...

Although Matplotlib has a wide variety of built-in colormaps, there are scenarios where you would want to customize your colors. The key tools for creating custom colormaps in Matplotlib are ListedColormap and LinearSegmentedColormap. Creating a custom colormap with ListedColormap ListedColomap al...
Sequential: change in lightness and often saturation of color incrementally, often using a single hue; should be used for representing information that has ordering. Diverging: change in lightness and possibly saturation of two different colors that meet in the middle at an unsaturated color; should...
Diverging: change in lightness and possibly saturation of two different colors that meet in the middle at an unsaturated color; should be used when the information being plotted has a critical middle value, such as topography or when the data deviates around zero. Cyclic: change in lightness of...
自定义 colormap 通常要使用 matplotlib.colors 模块中提供的函数和方法。 matplotlib.colors 是用来转换数字列表或颜色参数为 RGB 或 RGBA 的模块。RGB 和 RGBA 是具有3个或4个浮点数且数值在 [0, 1] 之间的序列。 创建colormap 时通常需要以下两步: ...
Builtin colormaps, colormap handling utilities, and the ScalarMappable mixin. class .ScalarMappable(norm=None, cmap=None) [source] Bases: object This is a mixin class to support scalar data to RGBA mapping. The ScalarMappable makes use of data normalization before returning RGBA colors from the ...
