st: [Stata 9] scatter axis bug

[David Airey <david.airey@vanderbilt.edu>]

I have some weird behavior in a simple scatter plot. The choice of  
axis range takes on the range of the data if one looked at each  
variable one at a time, but not the range of the plotted data. For  
example,

. d ln_rna hrsd17

              storage  display     value
variable name   type   format      label      variable label
------------------------------------------------------------------------ 
-------
ln_rna          float  %9.0g
hrsd17          byte   %8.0g

. scatter ln_rna hrsd17  // <-- gives a bad graph with lots of white  
space around the cloud

// y range 2 to -2, x range 10 to 35
// from below it should have reflected the common range

. summ ln_rna hrsd17

    Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
      ln_rna |        69    .5711169    .6988654  -1.479932   2.003551
      hrsd17 |       107    22.31776    3.664202         11         33

. summ ln_rna hrsd17 if ln_rna < . & hrsd17 < .

    Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
      ln_rna |        32     .569358    .7230897  -.6635817   2.003551
      hrsd17 |        32          23    3.360108         16         31



// a simple example of the problem:

input y x
1 .
20 50
30 40
40 30
50 20
. 1
end

scatter y x

// gives the range of the scatter plot as 0-50 on both axes--this  
looks stupid--can we fix this?

// also can we fix copying a graph to the clipboard that is > 72 dpi  
on the Mac? Still copies with a distorted
// x axis if the x axis > 72 dpi
