Hi, I have some graphs with lower and upper limits. I found a couple of ideas online, but nothing like "plotting symbols" like arrows. I am using the mathtex upperarrow symbol but it is quite unconfortable positioning the tex character in the righ X-Y position. Do you know if there is an easier way to plot arrows as "markers"?

This shows how to plot upper/lower limits errorbars ... (if this is what you need) |

If you're like me and what you want is just an arrow mark with its head at (x,y), you may use scatter() with custom verts. arrowup_verts = [[0.,0.], [-1., -1], [0.,0.], [0.,-2.],[0.,0.], [1, -1]] arrowdown_verts = [[0.,0.], [-1., 1], [0.,0.], [0.,2.],[0.,0.], [1, 1]] scatter([1.],[1.], s=100, marker=None, verts=arrowup_verts) scatter([1],[1.1], s=100, marker=None, verts=arrowdown_verts) -JJ On Thu, Jul 31, 2008 at 9:41 AM, Antonino Cucchiara <cuc...@as...> wrote: > Hi, > I have some graphs with lower and upper limits.
