Hi Rene, I have attached the canvas.root. However, I don't think that the thing with the error bars that I mentioned is actually a 'problem' as such, because in the tutorials etc., the error bars do look the same as what I'm getting. It's just that the error bar lines do not go all the way to the marker. There is always a slight gap. If you do not set the marker style to anything then things are fine. However, if you want a marker then there is this gap. Ordinarily, it is fine, but if the error bars are very small anyway, then you end up not seeing anything of them. The other thing is that the c1->RedrawAxis() works great for the actual axes (thanks very much) but is there anyway, to redraw the whole frame (in particular the right hand vertical side of the frame). What I should have said before, rather than 'FillColor' was if you have a 'SetLineColor'. then your histogram gets drawn in whatever colour you've chosen but where ever the histogram touches the frame, the frame goes that colour. Obviously the redrawAxis gets rid of it for the bottom and left hand lines, but not for the right hand line.
