Easy multi-panel plotting with grcomb Alex Gamma Swiss Stata User - PowerPoint PPT Presentation

Easy multi-panel plotting with grcomb � Alex Gamma Swiss Stata User Group meeting Bern, Switzerland 17.11.2016

Content ◦ The problem ◦ Enter grcomb ◦ grcomb in action ◦ grcomb syntax ◦ Limits & improvements

The problem ◦ Quegging (Quick Exploratory Graphing) ◦ Stata’s graph combine too complicated o need to produce single graphs fi rst o combine using graph combine o does not support wildcards in graph names

The problem . hist SCL_01, percent name(scl01) . hist SCL_02, percent name(scl02) . graph combine scl0* . scl0* is not a memory graph r(198);

Enter grcomb . ssc install grcomb ◦ requires ≥ Stata 10

grcomb in action . grcomb hist SCL_0*, percent v(1) 15 20 15 10 Percent Percent 10 5 5 0 0 0 10 20 30 40 0 10 20 30 40 SCL_01 SCL_02

Limits & improvements ◦ Combined length of variable names cannot exceed 244 abab) is default; should be o ◦ o ( ( aabb) ◦ No options of graph combine ◦ No other luxury ◦ The fi rst two will be addressed in a future update on SSC ◦ The second two are features
