I'm not sure if this would work, but you can save the predicted values
from the smooth, and then plot those predicted values. You should then be
able to use whatever graphics command you would generally use to truncate
the graph.
I don't know what you do to do the kernel density, for -lowess- I have
done the following to create the variable:
lowess y1 x, gen(predvalue1) nograph
lowess y2 x, gen(predvalue2) nograph
lowess y3 x, gen(predvalue3) nograph
.
.
.
lowess yJ x, gen(predvalueJ) nograph
Hope this helps.
