Make graphs square - or any other shape 

        sqr graph_command varlist [if exp] [in range] [[weight]]
            [ , aspectratio(#) graph_command_options ]


Note: This program requires Stata 7 as a minimum. In Stata 8 and up, it applies
only to old-style graphs produced by gr7. The only reason to try to use it in
Stata 8 and up is to apply it to such graphs, in which case graph here should
be understood as gr7. Otherwise, find the aspectratio() option.


Description 

sqr is a command prefix to place before any graph command to make graphs
square. Optionally, other aspect ratios may be specified.  For example, many
time series plots look better with low aspect ratios such that individual line
segments are closer to 45 degrees from horizontal.


Remarks 


sqr works by using the bbox() option of graph. This will be possible so long as
either (1) graph_command is itself graph or (2) it is set up to call graph with
any user-specified options of graph, and does not specify bbox() itself.

sqr does not control the shape of the data region, but the shape of the whole
graph image. Nor is any adjustment made to (e.g.) size or positioning of
lettering.


Options

aspectratio(#) specifies an aspect ratio (height / width) for the total graph
    image. In practice, aspect ratios between about 0.2 and 2 are possible. The
    default is 1 (square).

graph_command_options are whatever options apart from bbox() are allowed with
    graph_command.


Examples (Stata 7)

    . sqr graph mpg, by(foreign) box

    . sqr tsgraph vol, a(0.4)

    . for num 0.2(0.1)2, pause: sqr graph mpg weight, a(X)
