Re: st: Question about graph bar

[Alan Neustadtl <alan.neustadtl@gmail.com>]

Here is a way to create a variable that you can graph -over- and then
use the sort suboption.  Compare the two bar graphs created by the
fopllowing code:


/* Create small dataset */
clear *
set obs 100
generate x3=10+int((20-10+1)*runiform())
generate x1=30+int((40-30+1)*runiform())
generate x2=70+int((90-70+1)*runiform())

/* Use stack to create an "over" variable & graph */
preserve
  stack x1 x2 x3, into(x) clear
  graph bar x, over(_stack) name(g1, replace)
  graph bar x, over(_stack, sort(1)) name(g2, replace)
restore

Best,
Alan

Each variable is an indicator for whether or not the survey respondent answered yes to a question (and the respondent could have said yes to multiple questions).  I would like STATA to order the bars (variables) by the mean (most frequent --> least frequent).  Is there an option or anything that will do this?  I know I can do this manually by ordering the variables in the graph bar command based on their means, but I thought I would check if there is a more automatic way.
