st: -sparkline- revised on SSC

[Nick Cox <njcoxstata@gmail.com>]

Thanks as usual to Kit Baum, a revision of -sparkline- is available on SSC.

-sparkline- was announced in

http://www.stata.com/statalist/archive/2013-01/msg00922.html

and a revision was announced in

http://www.stata.com/statalist/archive/2013-02/msg00824.html

and the explanation and advice given still applies.

Scott Merryman alerted me to poor handling of string variables
supplied to the -over()- option; this is fixed. Thanks to Scott for
his vigilance. Otherwise, the help file has been revised with an extra
reference.

Nick
