RE: st: Precision and ordering issue in histograms titles
I mentioned in my initial post that:
"So, after reading some of the previous posts on the precision issues in
Stata I concluded that one way to achieve nice titles would be to create a
string variable, i.e. gen Xstring=string(X). Now the titles of the plot come
out fine when I replace <by(X)> with <by(Xstring)>. The only problem is that
the plots do not come out ordered by X (i.e. from the smallest X to the
largest X) anymore..."
So, I did see the solution you mention but then the problem has to do with
the ordering of the histograms...
Is there any way of getting around the precision issue without losing the
ordering of the histograms? (in my case I have 15 histograms and I would
like to have them ordered by X)
Thanks,
MA

One answer is to be found in a concurrent thread:
. gen SX1 = string(X1, "%02.1f")
. twoway histogram mpg, by(SX1)
