Hello
I have the following survey data of 1000 patients collected over 15
months:
Each observation contains the following variables:
X: "1" for using drug x and "2" for not using drug x
DATE: Day and month patient was enrolled in study (variable DATE as day
month year)
Adult: "1" yes "2" no
I would like to plot the percentage of patients who were using drug x in a
given month vs. month & year. So the axes would be Y: "percent of
patients using drug x in given month" and X axis: "month & year of
enrollment"
I cannot seem to figure out an easy way to do this. It seems that I have
to generate many variables to get a simple percentage of patients who were
using drug x for that particular month and then to plot it.
Also, I would like to get more sophisticated as well: the same graph as
above but have two lines on one graph; one line would represent the data
for children and the other for adults.
Also, I'd like to generate many graphs using the do editor (same as above
for other drugs). When I try using the do editor this, I get one graph
and then the next is shown and I get to save only the last. Is there a
way I could run several graphs using the do editor and then save them all
so that I could view them leisurely?
I have a copy of Mitchell's excellent book on STATA graphics and still
can't figure this out!
Appreciate any suggestions.
