[postgis-users] ST_AsBinary

[Kevin Neufeld]

Nice rendering decoration Michael ... I didn't know that was in OJ.

Or if you want, here's a simple plugin I use with OJ that exposes 
jfreechart for displaying the 3rd ordinate.  There's little in terms of 
code comments as it was just a quick hack that I found very useful to 
display the side profile of a river dataset I once worked on.  Just drop 
the jar along with jfree:jfreechart-1.0.13.jar and it's dependency, 
jfree:jcommon-1.0.15.jar, in the OJ extension directory.  CTRL-Z 
activates the plot on a selected feature.



Cheers,
Kevin
