Arjen, Further testing shows that the values being passed into the plplot functions are being truncated to 12 d.p., despite having "set tcl_precision 17" at the top of the procedure. Turns out I need set ::tcl_precision 17 to set the global variable. With this change tcl example 29 now works correctly. So we now have a working example 29, however we (probably Arjen!) should fix the code to use tcl_precision when returning values from plplot, and not just assume 17.
