I get what I expect in the first and third histogram commands, but not
the second. The bars are stretched widthwise in the second histogram,
such that I don't think the density adds to 1. In some twoway commands,
changing the xscale to log when you have estimated a model on x and not
log(x) is an incorrect procedure. Is this another instance? If so, I
think it should be disallowed. Easy graph dialogs should be easy.
Stata replied:
It was probably not a good decision to include the xscale(log) and
yscale(log) options with "Easy Histogram". These options only adjust
the scaling of the axis and do not log the data. In retrospect, these
options do not belong on the "Axes" tab of "Easy Histogram" and
therefore they will be removed. Look for the change in the next
ado update.
I now write:
But does it _ever_ make sense to include this as an option for the
histogram command? In twoway scatter it does, but in histogram it
doesn't, since the area will not sum to 1. Am I wrong?
