{title:What is a by-graph?}

{pstd}
A by-graph is a single graph (image, really) containing an array of separate
graphs, each of the same type, and each reflecting a different subset of the
data.  For instance, a by-graph might contain graphs of mpg versus weight,
one for domestic cars and the other for foreign.

{pstd}
By-graphs are produced when you specify the {cmd:by()} option;
see {it:{help by_option}}.


{marker remarks2}{...}
{title:What is a bystyle?}

{pstd}
A {it:bystyle} determines the overall look of the combined graphs, including

{phang2}
    1.  whether the individual graphs have their own axes and labels or
	if instead the axes and labels are shared across graphs arrayed in the
	same row and/or in the same column;

{phang2}
    2.  whether the scales of axes are in common or allowed to be different
	for each graph; and

{phang2}
    3.  how close the graphs are placed to each other.

{pstd}
There are options that let you control each of the above 
attributes{hline 2}see {it:{help by_option}}{hline 2}but the {it:bystyle}
specifies the starting point.

{pstd}
You need not specify a {it:bystyle} just because there is something you want
to change.  You specify a {it:bystyle} when another style exists that is
exactly what you desire or when another style would allow you to specify
fewer changes to obtain what you want.
