How do I select data from a quiver plot?

I have position (x,y) and velocity (u,x) data plotted as a quiver plot. I would like to select only a subset of the data to analyze. Ideally, this would be done with the brush and then saving the brushed data to a variable. However, the brush tool does not work with quiver. What's a useful workaround?

quiver(x,y,u,v), hold on
plot(x,y,'*'), brush on
