Re: st: Plotting string variables with sencode
Thank you very much Roger that does help tremendously. I wonder if you
or anyone else may also be able to help me with another graphical
problem I'm having?
I would like to truncate these plots (either the ecl or rcap plots) so
that I can 'magnify' the area where the very small (at present
invisible!) confidence intervals are. Some of the upper and lower
intervals will be outside of the range that I would like, however the
estimates would still fall into the new shorter range. I know of the
truncate option that can be applied to version 7 metagraph but eclplot
(and rcap) doesn't allow it. Does anyone know a way of doing this please?
I am hoping to keep all the intervals in the plot b

Dear Stata list users,
I am trying to produce a graph that is essentially a forest plot
using a combination of a scatter plot and a twoway rcap plot. I have
gone down this route as I have found the metagraph and eclplots are
not exactly what I need. I have estimates with very different
weights and those that are weighted heavily completely engulf the
other lightly weighted estimates when metagraph is used (I have tried
changing the scale of the weights in the plot and this doesn't help
as the smaller weights disappear). The [w="a weight"] option does
not work with the eclplot command.
So using the my scatter and rcap plot I need to plot the
alphanumerical id of the estimates on the y axis. I have used
sencode to produce a new variable that, if I'm correct in thinking,
is numerical but keeps the alphanumerical part as a label. Now when
I use this variable in the plots I would like the labels to be
displayed (automatically preferably to me specifying each individual
label using ylabel(1 "" 2 etc)) rather than the number.
Does anyone know how I can do this please?
If you use the option
then the axis labels will be value labels. Otherwise, the axis labels
may be value labels or formatted values, depending on the scheme.
Another tip. -eclplot- can do symbols weighted by study size. It does
this by specifying weights as part of the -estopts()- option. If you type
eclplot estimate min95 max95 study, estopts(,[aweight=studysize])
(note the comma before the weight), then the estimates will be
weighted by study size. And you can also use the -supby()-,
-estopts1()- and -estopts2()- options to make the symbols squares for
the individual studies and diamonds for the combined meta-analysed
estimates. See the on-line help for -eclplot-.
I hope this helps.
