st: Formatting a twoway graph with different scaled y axes

[René Geppert <geppert.rene@googlemail.com>]

Hi, I am using Stata/SE 10 for Windows.

I generated a graph using the following (simplified) code:

. twoway (bar var1 Quarter, yaxis(1) yscale(range(0))) (line var2 
Quarter, yaxis(2) )

I do so in order to obtain two y-axes (left and right hand side) with a 
different scale. To format the graph properly I experienced two problems:
a) Both axes start at their minimum values, which I can fix for the left 
hand side y-axis using yscale(range(0)), which does not work for the 
right hand side y-axis for some reason. Why is that and how can I 
achieve the same effect there?
b) var 1 and var 2 have 6 observations (at each instance of Quarter). 
How can I get a label at each instance in the graph for the line and bar 
plot, respectively? That is, show the observation values for example 
inside each bar and above the line. The blabel option which one can 
usually use in a bar graph does not work in the twoway bar version.

regards, Rene
