Hi Stu,
The drawing editor can be used as a display for arbitrary shapes. It can read 
an "xgrf" format. This format is not documented but it is  easy to create. 
First, interactively create a drawing tool. Go draw some lines, etc. From the 
control's file menu export the drawing to a .xgrf file.

This is a simple xml format that allows you to specify the coord system, 
points, color etc. So you could just generate one of these files with your 
data. Then load the file in as a data source. A non-interactive drawing control 
will be created.
