Help with line graphs

[Adam Alhassan]

Hello,

Could someone kindly help with plotting a graph showing trends of time. This is a study looking at age-adjusted prevalence of asthma from 2005/6 to 2017/18. I am trying to create a graph trend with proportion on the y-axis and year on x-axis, with a line connecting proportion during each cycle. Also, how does one plot trends stratified by a third variable, race for example?
I'm using the NHANES database and because it's a 2-yr cycle, I'm unclear as to how to label the x-axis to reflect the 2-year cycles.
I would be grateful if anyone in this community could help.


Rows: row number
Year: NHANES cycle years
Proportion: national estimate per cycle
SE: Standard error
low: Lower limit of CI
high: Upper limit of CI

end

Code tried:
set scheme s1mono
encode Year, gen(year)
twoway (rcap low high Rows, vert) (scatter Proportion year, sort connect(l))
