I am not sure what you mean by this. My previous assumption was that the
issues related to parameters that typify a histogram (beyond a normal line
chart) are:
1. The borders of each step.
2. The width, position and height of each step.
3. The correct labeling of each step (which I assume will be sorted out
now that we can use a continues data axis)

Is this situation any clearer yet?

I did run your example code and attached is the result. Something looks
like it is not working. Any suggestions?
