Xlabel Bar Graph

[Christoph Steinert]

Why can I not change the xlabels of by bar graph from numbers to meaningful names? I get always the following error messages:

xlabels(1 PGM" 0 "PGM invalid name
r(198);

 #delimit ;
graph bar (mean) prelapse, over(pgma)
bargap(-30)
note("Source: Created by the author based on PGMD and UCDP data")
scheme(s1mono)
blabel(bar, position(outside))
ytitle("Percentage of recurring conflicts to total number of conflicts")
xlabel(1 "PGM" 0 "PGM absence")
title("Relative frequencies of conflict recurrences")
ylabel(0 "0%" 0.2 "20%" 0.4 "40%" 0.6 "60%")
name(grapha, replace);
#delimit cr

Wrong option. xlabel() is not an option of graph bar. The error message is puzzling, but the syntax is not legal.

Thanks! But is there another way to label my x-axis meaningfully?

Christoph Steinert if the variable displayed on the x-axis has value labels associated with the values and you have brewscheme installed you can create a theme file that will default to using the value labels:

// This will only modify changes from the default theme used by brewscheme and is based on the code above
brewtheme extheme, yesno("use_labels_on_ticks yes") barlabelsty("bar bar") barlabelpos("bar outside") relsize("bar_gap -30")

// Create the new theme file using a gray scale color palette for all graph types and the theme created in the line above
brewscheme, scheme(exscheme) allsty(greys) allc(6) themef(extheme)

// Create the graph with the new scheme and never have to code the same set of aesthetic settings again in the future.
gr bar (mean) prelapse, over(pgma) note("Source: Created by the author based on PGMD and UCDP data") scheme(exscheme) ///  
yti("Percentage of recurring conflicts to total number of conflicts") ti("Relative frequencies of conflict recurrences") name(grapha, replace)

Haven't had a chance to test it, but assuming the values you are trying to use on the x/y axes are defined as value labels on their respective variables it should get you a good amount of the way there.

See help graph_bar##axis_options . In particular, see relabel() under the over_subopts section. You will want something like:

...over(pgma, relabel(0 "Text" 1 "Text") )...
