Re: st: axis bar starting from 0 on graph (not the label) |

Yes and no. You can always add a line at y = 0 by -yline()- and make that as emphatic as you like by varying its width and colour. Making this a light line and the background a little darker can work as well as making this a dark line against a light background. You would have to fight Stata every stop of the way if you wanted to move axis labels, ticks and titles. You'd need to re-create your own. Stata's bias is that although people do sometimes want axes running through the graph, they usually end up very messy, so it won't play willingly. Most statistical software seems to have moved away from the conventions that the axes must be the lines y = 0, x = 0 as high school algebra insists and to separate out the functions of titling, labelling and ticking from showing where the zero lines are. That does not rule out something clever with the Editor or Stata's class language, except that I don't know what it is. If you have access to MS Excel, what you want is I think the default any way, as is all too evident from work I often see. The essence of the problem is that if data points or line can be negatives they often collide with axis stuff.
