RE: st: How to start a bar graph with a minimum other than 0

[Andrew Hsiao <ahsiao@newvisions.org>]

I just studied the command yscale(range(x y)) in the document a bit more. It seems it is not used to define the range of axis to be shown on the graph. Rather it is used to EXPAND the range of the values in the data. So it does seem that Stata does not allow "cheating" to truncate the bottom part of the graph.

It looks the solution is to find the aggregate of the variables (group means) and plot the values directly, using range(50 100) to define the bottom of the graph.

Then try cheating.

1. Subtract a constant value from each mean (looking at your data, you might subtract 70)

2. On the plot, use bogus labels

ylabel(0 "70" 5 "75" 10 "80" 15 "85 20 "90", angle(0))
