Hi,
I'd like to know whether its possible to draw a scatter plot with
both point-to-point connections and cubic splines.
To illustrate the problem, consider the following data.
---------- data begin -----------
input y x
0.5 1
0.1 2
0.2 3
0.7 4
0.9 5
0.4 6
0.3 7
0.7 8
0.5 9
0.2 10
end
---------- data end --------------
The following command draws the graph with each points of y
connected together.
graph y x, c(l) s(o)
I can also draw the graph with cubic splines to show the
"tendencies" of y. This is done using the -bands()- option.
graph y x, c(s) s(o) bands(4)
My problem: I would like to have a "combined" graph with one of
the above graphs superimposes onto the other. That is, I want to
have a graph that shows both kinds of lines: point-to-point
connections, and the cubic splines.
Does anyone know how to do this?
Many thanks.
HJW
