I'm using -dotplot- (comparative scatterplot) with multiple variables (second
syntax) and using the options for median lines and shoulder bars. If I don't
specify the marker symbols, the median lines appear as three plus sign markers
and the shoulder bars appear as three minus sign markers. If I do specify the
marker symbols for the data points, the median bars and shoulder lines appear
as that marker symbol shape in motley colors. These lines appear to be
overlaid plots using the next color in the scheme-stipulated sequence of colors
for successive plots.
I would like for the median lines and shoulder bars to appear as solid black
lines and dashed black lines, respectively. I've checked the manual and on-
line help, and even glanced at the ado-file. There was a thread on -dotplot-
on Statalist last October, but it wasn't about this problem.
How can I get -dotplot- to use connecting lines instead of marker symbols for
the median lines and shoulder lines? Absent that, how can I specify that the
scatterplots for the median lines and shoulder lines revert to plus-sign
symbols and minus-sign symbols when I specify marker symbols for the data
points?
