Re: [OctDev] regress and rcoplot (partially written, please help)

You should just be able to use errorbar.

Assuming you don't want to because you don't like how it looks, can you 
set the symbol size larger instead of drawing circles yourself?

    __gnuplot_set__('pointsize 2'); plot(rand(5,1),'o;;');

I would suggest plotting using:

   plot(cx,cy,'o;;',lx,ly,'-;;')

where cx,cy are the points and lx,ly are matrices with three columns 
and two rows for each r defining the end points of the error bars and 
the caps respectively.

If you decide to draw the circles yourself, change this to:

   plot(cx,cy,'o;;',lx,ly,'-;;')

where cx,cy contain one column per circle.

No for loops needed, and a small number of separate matrices being 
plotted should improve your performance a lot.
