st: Bug in yscale(range()) option?

[Jan Paul Heisig <jan.heisig@wzb.eu>]

Hi all,

I am trying to construct twoway graphs using the "yscale(range())"
option to extend the range covered by the y-axis (both at the lower and
upper ends). My outcome variable only takes negative values and it seems 
that range() works as it is supposed to at the lower, but not at the 
upper end, at least as long as the upper end takes a negative value.

The following example illustrates the problem (in particular the second
graph):

version 12.1

sysuse auto, clear

scatter turn foreign, yscale(range(10 80))

gen minturn=-turn
scatter minturn foreign, yscale(range(-80 -10))

scatter minturn foreign, yscale(range(-80 5))

Is this a bug?

Many thanks,
Jan
