Thanks for the explanation, Nick. I similarly found that a plotting a single variable mapped the marker labels correctly, which allowed me to explore the data as I wished, although in a less data-dense fashion (which my boss would probably say is better anyway!) I tend to like fewer charts with more information in them. -JW -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Nick Cox Sent: Wednesday, October 27, 2004 3:10 AM To: statalist@hsphsun2.harvard.edu Subject: st: RE: Bad dotplot command? A -dotplot- to Stata is really just a special kind of scatter plot. The trickery within -dotplot- is to map the values of one or more variables to the coordinates needed to produce this scatter plot. When you ask for a -dotplot- of two or more variables, rather more is involved than with just one. In the temporary restructuring of your dataset that's required, not everything that might be needed for a plot is carried over. In particular, marker labels are, as a side-effect, not supported. I imagine that programming that was just a complication too far as far the programmer was concerned, but that it was decided to trap such requests. Most people who produce dotplots just use plain symbols, I imagine. I just checked with the unofficial -onewayplot-, which offers a similar display, and found that in effect I made a similar decision, although it is not trapped at source. In short, I surmise that your request is reasonable but at present just not supported by -dotplot-.
