Creating a combined graph

[Jane Buerckner]

Hi,

I'm struggling to get this right. I have 2 variables that I want to show on a single graph. Firstly, is % of patients who survive (currently variable is ynAlive, a binary outcome) and second is how fast they were defibrillated (DCCS, measured in whole minutes as an integer).

Ideally, the graph would show % on the y axis and minutes on the x axis. There would be two lines - line 1 showing survival % decreasing per minute increase in DCCS, and a second line showing currently what % of patients are defibrillated per minute.

graph bar (percent), over(DCCS) gives me the correct graph for the second part (although I want line not bar and when I specify line I get "linegraph_g.new (percent), over(DCCS): class member function not found"

I feel like this should be relatively simple but I just can't wrap my head around it.

Thanks all for your assistance.

This is hard to answer without a data example.

graph bar is a long way from twoway line. You need to calculate percents first and then call up line.
