Re: attributes and resources

Hi Diane,

You can set up your resources first, then use attsetvalues to apply the
user resources. The user resources would then override your settings.
For instance:
plot = create "plot" logLinPlotClass wks
       "trYMinF" : min(y)-2
       "trYMaxF" : max(y)+2
       "trXMinF" : min(xAxis)
       "trXMaxF" : max(xAxis)
       "pmTitleDisplayMode": "Always" ; allow titles
       "tiMainOn" : True
       "tiMainString" : ""
end create
if (plotres) then
    attsetvalues(plot,userres) ;if user resources are present, use them
end if

Good luck,
Adam
