lsens graph marker size

[Nick Bornschein]

Hi,

I'm using lsens after a logit regression and the marker size is way to big. I tried "lsens, msize(vsmall)" which changes the marker size of the sensitivity marker very well, but the specificity keeps unchanged. How can I change it via an option?

The source code reveals that both graphs are drawn using

connected x y z

which will allow changes only to the last graph in order. However, the inputs for the graphs are available via options, so you can use twoway to achieve what you want. Here is an example

webuse lbw, clear
logit low age i.race
lsens, genprob(cutoff) gensens(sens) genspec(spec) nograph
format cutoff sens spec %9.2f
set scheme s1color
twoway (connected sens cutoff, sort msize(tiny)) ///
(connected spec cutoff, sort msize(tiny) ///
ylabel(0(.25)1, grid) ytitle("Sensitivity/Specificity") ///
xlabel(0(.25)1, grid) xtitle("Probability cutoff") title(""))

Working on a different problem, I now realize that in plots with multiple graphs, you need to specify an option several times to affect the rendition of the graphs. Perhaps this should be better explained in the manuals. The workaround in #2 is therefore not needed.
