在我的工作中,我也想使用这一类型的colormap,但特殊之处在于我希望X颜色不是取到中间,而是靠近右端点的位置。例如v=12,取深红色;v=50,取白色;v=57,取绿色;端点之间颜色渐变: 为了实现这一功能,需要介绍matplotlib的LinearSegmentedColormap。 我修改了官网Creating Colormaps in Matplotlib — Matplotlib 3.9.2 ...

There are also external libraries that have many extra colormaps, which can be viewed in the Third-party colormaps section of the Matplotlib documentation. Here we briefly discuss how...
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: ...
