Hi,
Can anyone help me with this?
I am trying to write a program that plots the functions a + bx + cx2 (on
the same graph), where a, b and c are stored variables. I want to label
the legend with the set of values a, b and c for each graph.
For example if I have:
a b c
1 3 4
2 5 8
then I want to have "a=1, b=3, c=4" and "a=2, b=5, c=8" assigned to the
relevant graph in the legend. How can I do this? Also , how complicated
would it be to control the colours or line types of the graphs?
My current program is as follows:
program define polysameplot
foreach i of numlist `0' {
local gr "`gr' function y=a[`i']+b[`i']*x+c[`i']*x^2, range(-5
5) ||"
}
twoway `gr'
end
polysameplot 38 39 40 41
I use Stata 10.
Thanks a lot for your help!
