Hi Statalisters,
I use Stata 9.1 for Windows XP. I am trying to draw what is supposed to be
a simple bar graph. I experimented with and compared the "graph twoway
bar, horizontal" and "graph hbar" commands. Please find below sample data
and commands for illustration. First I tried the "graph twoway bar,
horizontal" command. The resultant graph (GRAPH_01) was very close to what
I wanted except that there was a small gap between the y axis and the
location where bars began. Then I tried the "graph hbar" command. The
resultant graph (GRAPH_02) took care of what I found lacking in GRAPH_01
but it displayed the labels of categories which I wanted to be invisible
(that is, I wanted to create a gap between hospital categories); those
categories are 3, 6, & 9 on the y axis.
Does anyone know:
1) How to eliminate a gap(space) between the y axis and the location where
bars begin in GRAPH_01, using the "graph twoway bar, horizontal" command?
2) How to make the labels 3, 6, & 9 on the y axis (the categories intended
to be invisible for an aesthetic reason) disappear, using the "graph hbar"
command?
