在mayavi / mlab中更改颜色图标签

Question

I'm doing a quiver3d plot with vector length scaled by log(length)+5 in order to visualize a large range of lengths between 0 and 1. Is there however a way to change the colormap back to the original values while showing a logarithmic scale? I would like to do this purely in python, because if have problems running the mayavi GUI.

Answer 1

我不知道有什么好方法，但是我可以想到一个可能很容易做的怪异的事情：用正确的颜色图创建一个不可见的虚拟对象，并显示该对象的颜色条。

Answer 2

I am not sure whether this helps in your case but you could use quiver3d's scale_factor argument to limit the maximum quiver length. But that is of course linear scaling, not logarithmic.
