Is it possible to draw an histogram with no vertical lines at all (and default options)? The same visual effect can be achieved for example setting errors to a number very close to zero and then drawing with the “E” option.
You want an horizontal bar at the Y position of each bin, the length of the line being the bin width ?
There is no predefined option doing that, but the attached example does it.
