[Matplotlib-users] Problems with the arrow head size in 3D

[谢瑾博]

Hi everyone,
 I have been trying to draw the topo with arrow head shown as follow. However, for a typical topo (1000~6000), the arrow head will not show, and show a line only. This size of the arrow head seems to be sensitive to the range of the Z axis (as in the second picture, the head shows better when range is 1~5). I wonder if there is a set source to tune the size of the arrow head?
yours, 
Jinbo
