Standard Error Bar Chart
[edit | edit source]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
[edit | edit source]- the list of symbols :
. palette symbolpalette
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
[edit | edit source]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.
