 # Matplotlib quiver

Dear Matplotlib help,

I have successfully created plots with quiver. The script is working.
However, I want to create multiple plots (quiver) with different datasets.
Due to the differences in datasets the length of the quiver is changing in
each plot. How can I keep the quiver length same in each plots? Note, I do
want variations in quiver length in the plot. I don't want the length of
each quiver equal in same plot.

I am using below in my script.
Q=ax.quiver(x, y, u, v, pivot-'tip')
qk = ax.quiverkey(Q, 0.78, 0.78, 5, '5 mph', labelpos='E',
coordinates=figure')

1. scale function will not work.
2. Normalizing the data will also not work

Why do you say this? If I understand your question correctly, setting
the scale and scale_units keyword arguments to the same value in each
plot should do what you need.

e.g.

Q=ax.quiver(x, y, u, v, pivot-'tip', scale=10, scale_units='inches')

Bingo, it worked. I was using scale alone so it was not working. But worked
with scale_units.

Thank you Eric.
