Re: Plotting Spline within a script

[Thom Burnett <Thom.Burnett@cognigencorp.com>]

Vincent,

Thanks for you help.

I'm using the graphsheet in windows and don't know how to combine your 
code with a graphsheet.
From what I've read graphsheets use the methods guiCreate() guiPlot(), 
guiModify(). I'm not sure how the
standard graphics or the trellis graphics can be made to fit in.
