Hello,

  Gist is a nice package for what it does. I think it makes a good foundation
  for a lot of 3d type of work, but falls short of :

  At least one person's idea of what it should do. I am had some frustration
  with trying to get bar graph and non-numeric ticks. I also would like to
  get 2 different XY axis for the graph, which I don't think is supported
  in Gist. Basically I will be extremely satisfied with Gist + Excel type
  of graphics. Has anyone seen Splus 4 graphs in Axim? It's completely obj
  oriented. Would it be lovely to have Trellis type of analysis? 
  Just my few thoughts,
  
Hoon,
