Dear All

I have the same problem:
I have a set of vectors; I want to plot a sub-set B in blue and another sub-set (R) in red. The obvious for me would be

quiver(xB,yB,U,W,scale,'b','Autoscale','off'); hold
quiver(xR,yR,U,W,scale,'r','Autoscale','off');

xB and yB are NaN where xR and yR are finite but this is irrelevant.

The output scales are apparently different; vectors of the same length are ploted with very different lengths.

Is this a bug? how do I correct this? Hua's solution does not seem to work for me.

Thanks for any help.

Rui
