Ooops, it should have been 100k points

 The way I used to do it:


  ------------------ -> XY Events --o--> xy Events   ----------
 |                  |               |               |          |
 |  Plotting widget |            Scales             |   Model  |
 |                  |                |              |          |
  ------------------  <-  Plot(XY) <-o- BigPlot(xy)  ----------

 where XY are screen coordinates( int, int ) 
   and xy are "model" coordinates ( double, float ) 

========================================================================

PS. Is there any gnome_canvas documentation besides source the code
( libgnomeui and applications that use them )?
