Hello,
I use the following command to generate a categorized bar graph:
graph bar (asis) q41a if grandom == 1, over(frandom_)
However, I receive the following message:
variables frandom_ _variables do not uniquely identify the observations
I don�t understand why my "frandom_" variable need to identify the
observations uniquely.
(by the way I have an "id" variable which uniquely identifies observations)
I also do not understand what "_variables" refers to.
If I run the command without "asis" then I get the following:
graph bar q41a if grandom == 1, over(frandom_) variable __000006 not found
in using data
In particular, what I am trying to do is this: see the three tabulations
below. What I want is a categorized bar graph, where the categorization is
over frandom. That is, three bars in a bunch will present together "Plan van
name5", where each bar refers to one of the "frandom"s. There will be three
bunches with each bunch having three bars. But unfortunately, I receive the
message I mentioned.
