st: twoway area with no outline along the baseline

["Nick Winter (UVa)" <nwinter@virginia.edu>]

Hi,

As part of a more complex graph I'm trying to construct, I want to 
create a -twoway area- plot that lacks the outline along the baseline. 
THat is, I want the outline along the "peaks" of the area, as well as 
along the vertical drops down to the baseline at the minimum and maximum 
of the data, but I do not want the outline along the baseline itself.

The two approaches that occur to me are:

(1) overwrite the baseline with an appropriate -twoway line-, with the 
line color set to the fill color of the area plot.  THe problem here is 
that when the area plot gets very close to the baseline, the outline of 
the peaks can get overwritten as well if it is close enough to baseline 
at some point along the area.

(2) create the area plot with no outline (that is, with the outline the 
same color as the fill), then create the outline with -twoway line-. 
This does not create the vertical drops to the baseline at the min and 
max of the data without adding fake observations.

I could do (1) and then (2), using (2) to re-create the line wherever it 
might be overwritten in step (1), but that seems inelegant at best...

Any other ideas?
