Stacked Bar Chart If Condition

[Patrick Zollner]

Hi,

I've run into a problem and I'm not sure how to fix it. I would like to include an if statement for a barchart I am producing. The data I have is in the form count type year, where count is the number of units for the type in the year.

egen count_total_by_y_t = total(count), by(year type)
gen count_total_by_y_t_k = count_total_by_y_e/1000
graph bar count_total_by_y_t_k, percentages over(engine) asyvars over(year) stack

This code produces the chart I would like. However I would like to limit it to a select few types. Type is categorical and ranges from 1-8. How should I change the code so that the bar chart contains only types 2 to 5 for example?

Thanks

if inlist(type, 2, 3, 4, 5) or if inrange(type, 2, 5) is the usual kind of restriction. You don't usually need to calculate percents, as graph bar will do that for you.
