Re: st: detonator plot with three grouping variables

["Roger B. Newson" <r.newson@imperial.ac.uk>]

To plot multi-group detonator plots, you should use -eclplot- with the 
-by()- option, the -supby()- option, or even both. The -by()- option 
does by-groups in the usual way, and the -supby()- option allows you to 
create groups of adjacent bars, in which each bar in the group has a 
different color (or shade of gray).

A tutorial on -eclplot- (including detonator plots and the -supby()- 
option) is available as a presentation originally given at the 2005 UK 
Stata User Meeting (Newson, 2005).

I hope this helps.

Best wishes

Roger

I will use the links you have provided to make the case against using the detonator/dynamite plots but there is an even simpler case which is that the resulting plot will be quite busy. It is for this reason that I must make the plot. I will look at -ciplot- which, I think, does what David suggests.

I could do three different graphs for each of the highest levels (e.g rep78 in the demo example) but the point was to have one graph. On -stripplot- I am a true convert/believer and use it whenever I have the opportunity to.
