Hi Christine,

CIPLOT is showing proportions, not RR. I think you will have to create 
your own chart in another package. You can import the attack rate table 
into excel and with a bit of manipulation, get the columns in the right 
order for a "stock chart" - stock chart uses the order Close, High, Low, 
where Close will be RR, High will be UCL and Low will be LCL.

However, you will have to do some formatting to do to get the chart 
looking as good as CIPLOT.

The graph must show relative risk, lower confidence interval and higher confidence interval for each exposure. I have looked at the CI graph in Epidata Analysis but
