Standard Error Bar Chart
Standard Error Bar Chart are very useful to displain confidence interval.

. clear . set obs 100 obs was 0, now 100 . gen id = _n . expand 10 (900 observations created) . gen u = id/30 + invnorm(uniform) . collapse (mean) mean = u (sd) sd = u, by(id) . local s = invnorm(.975) * 97,5 percentile of the normal distribution . serrbar mean sd id, scale(`s')

Setting for Graphics
. palette symbolpalette
 * the list of symbols :

query graphics gives all the settings.

. query graphics Graphics settings set graphics       on         set scheme          vg_s2c set printcolor     automatic  may be automatic, asis, gs1, gs2, gs3 set copycolor      automatic  may be automatic, asis, gs1, gs2, gs3 set macgphengine   quartz     may be quartz or quickdraw set piccomments    on


 * The scheme defines the general appearance of the graph.
 * You can download more scheme on the Visual Guide to Stata Graphics website :

. net from http://www.stata-press.com/data/vgsg2/ . net install vgsg2

Exporting/Saving graphics
You can export a graph to png, jpg, ps or pdf format by using once the graph is done the graph export command.

. tw sc y x . gr export graph.png, replace

See h gr export to see the list of all available graph devices.

You can also store a graph in the Stata graph format using the graph save command. This format can only be read by Stata.
