Why is left and bottom side of the box disappeared?

I would like to plot a transparent bar histogram on a previous plot. I used the following:

b1 = bar(UMEAN,UHIST); set(get(b1,'Children'),'FaceAlpha',0.3)

The problem is that the left and bottom side of the box (the axes) disappeared. Not the tics just the edge of the box, and it is very uggly.

Do you happen to be using a log axes? If so then I am not sure you will be able to use transparency.

If not then try

opengl software

Setting transparency forces switching to opengl from the other renderers, so some things can come out differently. Sometimes there are bugs at the MATLAB level; sometimes there are hardware opengl driver bugs.
